Contribution How to start enjoying classical music late in your life Susumu Kitazawa It was about 15 years ago that I started enjoying classical music, so I am fairly a late starter. The kindling occasion was when I happened to listen to Symphony No.7 (Beethoven) by Vienna Philharmonic Orchestra conducted by Carlos Kleiber. It was a music that went forward in a rhythmical and forceful cadence, as was expressed figuratively by Wilhelm Richard Wagner as “apotheosis of the dance.” It changed an image in me that classical music is heavy and lengthy. I was gradually hooked on classical music. Initially like everybody else I wondered what music in the classical genre I should select among many. What I did was to listen to one piece of music after another which I encountered in introductory and guiding books available anywhere and programs in TV and FM radios. Classical music goes with peculiarity called “reproduced music.” What is meant by it is that composers passed away long time ago. Their music reproduced by one group of players and conductors are not the same with those by another group because the motif is changed with their own interpretation as there are few left on how to play the music in the original scores. If I compare several of Symphony No.5 “Fate” of Beethoven in my disc collection I can say this. In terms of playing duration Wilhelm Furtwängler/Vienna Philharmonic Orchestra goes with 35 minutes and 45 seconds, Carlos Kleiber/Vienna Philharmonic Orchestra goes with 33 minutes and 08 seconds and Herbert von Karajan/BPh goes with 30 minutes and 25 seconds. Not only the tune durations but the rendition of the music including the tempo and dynamics is largely different from each other. There are many renditions of the same classical music by different conductors and orchestras and musical critics say whatever they like about their performance. In such an environment it became a pleasure for me to listen comparatively to several different recordings of the same music and to view the performance of conductors in videos. I have not a small number of conductors I like, but I have never been disappointed by the aforementioned Carlos Kleiber (1930 – 2004). He is referred to as “the last charismatic conductor.” I am instantly drawn into the world of music by his lively, yet flowing and elegant performance. His dynamic and graceful posture viewable in videos goes even with atmosphere of a star. I came to know that Carlos Kleiber was ranked top among “The 20 greatest conductors in the history” featured in April 2011 edition of “BBC Music Magazine” of the UK. This was the result of voting by 100 conductors in active service. This fact implies that even conductors in active service wish to be a conductor like Kleiber in a sense. As his age advanced Kleiber had lessened his appearance on the stage, limited his repertoires and demanded higher level of performance by orchestra and opera houses. He even cancelled his appearance if he did not like whatever is expected by him. If he had been an ordinary conductor he would have soon lost his business. But his bearing like this has amplified his charismatic enchantment among music fans so much so that first rate orchestras in the world wish to be conducted by him. This fact proves that his music making is profound and thorough which kept audience captivated

If I were asked, “what orchestras do you like best?” My answer would not be specific because there are many excellent orchestras in Japan and overseas and their performance depends on the conductor and the music to play. However, I can say this at least. I have never missed the performance of Royal Concertgebouw Orchestra when they performed in Japan. Their music wraps us with sound which is refined, polished and rich if I may say so although it is beyond the expression by words. This orchestra has been led by six lead conductors in 125 years since its establishment. It is said that their long cultivated tone quality is unchanged although their performance changed from time to time. Although it is a bit too old but the December 2008 issue of UK music magazine “Gramophone” selected the world best 20 orchestras with Royal Concertgebouw Orchestra as the top. The editor’s comment in the issue went as follows in essence. “The orchestras we selected this time all stand out as being noteworthy for the excellence of “individuality” when there are so many orchestras sounding like the next orchestra if the sound is refined. Above all the Royal Concertgebouw Orchestra produces out “individuality” of composers as one of the last group of orchestras with unmistakable tone of sound just as an actor performs out his/her role on the stage. This convincing appraisal reflects the fact that orchestras in the world are losing their idiosyncrasy in general due to globalization occurring in the music world too where musicians and conductors perform in various orchestras interchangeably, which results in artistic quality leveled out. The best way to encounter one’s favorite conductors and orchestras is to go to concerts. Recent high quality audio equipment enables us to listen to music in Hi Fi, but you cannot beat the concert hall which encloses you with rich sound of music. Also recommendable is to attend lectures in culture classes on classical music in which you can learn many interesting anecdotes on composers, conductors and orchestras which will help you get emerged in the world of classical music. It is my intention to keep seeking opportunities to encounter with good music if I will have to go a roundabout way from time to time.

EMC Viewed from Signal Transmission – No. 9

Losses in Serial Transmission – Part 2 By Yuzo Usui

Frequency spectrum of pulse wave form 1) Transmission circuit is considered a kind of LPF (Low Pass Filter) because it has characteristics of letting the amplitude of passing signal attenuated at higher frequencies. The horizontal axis in Figure 6 of the previous article represents the frequency, but in serial transmission we deal with in this article is pulse wave form. Therefore, it is necessary to convert the frequency into the transmission rate (such as Gb/s). In serial transmission in general NRZ (Non Return to Zero) is commonly used. Since each bit is expressed with “0” and “1” the pulse width and transmission rate are in the inverted relationship each other. The pulse width of 1Gbps is 1ns and the pulse width of 2.5Gbps is 400ps, for example. Frequency spectrum of a pulse wave form can be obtained with Fourier transform. If you did Fourier transform on the pulse wave form in Figure 1, its frequency spectrum becomes –

TW t sin r TW sin 2 2 ................................................................................................................... (1) F       T  t T W r 2 2 As indicated here this is function only of the pulse width Tw and pulse rise (fall) time tr. Repeating frequency appears as line spectrum with this spectrum as envelop line. In the same figure the amplitude of the spectrum against the frequency is indicated. The horizontal axis is normalized with transmission rate (1/Tw). The same figure also carries amplitude enlarged in lower frequency regions against decibel in vertical axis in an overlaid fashion. In the field of analog the frequency band is expressed in frequency reduced by 3dB. This is the point where energy or electric power gets one-half. Apply this concept and you will get frequency bandwidth 0.4 times of transmission rate as the frequency lower by 3dB is 0.4. 1Gbps gets you 400MHz and 3.125Gbps gets you 1.25GHz.

If transfer rate and frequency are associated with each other in this fashion the point at which resistance loss and dielectric loss are crossed in Figure 6 of the previous article of this sires is approximately 2GHz, which is 5Gbps if expressed in the transfer rate. In frequency lower than this frequency the resistance loss is predominant and in frequency higher than this frequency the dielectric loss is predominant.

Frequency characteristics of line loss In Figure 6 of the previous article of this series the decibel scale of vertical axis is expressed in logarithm. Since decibel is originally expressed in logarithm here the logarithm is doubly effective. I have often been questioned about this fact. Generally frequency characteristics is expressed against logarithm of frequency. In other words x-axis for frequency is on logarithmic scale. On the other hand loss expressed in decibel is proportionate to frequency and root of frequency, so it is rational to express y-axis also in logarithm so that resulted characteristics is drawn in direct line. Line loss is made of combination of resistance loss caused by skin effect and dielectric loss caused by dielectric tangent. Therefore, in order to lessen the resistance loss it is necessary to make cross section large which is translated in wide conductor width. In order to lessen dielectric loss it is necessary to select materials with small dielectric tangent (tan σ). As I previously mentioned materials with dielectric loss as small as 0.005 is commercialized now which is one fourth of 0.02 of general FR-4. Figure 2 indicates line loss against the frequency by changing pattern width and dielectric loss as parameters2). Parameters are, pattern width=100μm and tan σ = 0.02 (common combination) vs. pattern width=400μm and tan σ = 0.005 (low loss combination).

As an aside, convert x and y axis of Figure 2 into direct scale and you get Figure 3. This chart is oftentimes used to express line loss, but it gives not much information in terms of electric nature. I assume that the readers of this series feel uncomfortable with x-axis being in direct scale. I hope you all feel comfortable with expression as in Figure 2.

Effects of loss against transmission wave forms Characteristics of line loss is that of low pass filter in essence. Therefore, it is easily assumed that transmission wave forms will become close to integral wave form. Figure 4 (a) is of wave form in the case of line length being 50cm. Its feature is that change in rise portion of wave shape goes in a gentle slope. Figure 4 (b) is of an example of circuit of 5cm long. Almost no line loss is observed in the graph. Figure 5 indicates comparison of step response between primary delay circuit and time response. The idiosyncrasy of loss circuit is that the signal gets blunted at rising time and drugs on for some time. Because of this idiosyncrasy inter-signal interference occurs when narrow pulses are repeated. I will discuss more about this next time.

3. Remarks While some of responses to questionnaires on the seminar collected were positive such as “Easy to understand,” “Basic technique for EMC design was very interesting” etc. there also were negative ones such as “Difficult to understand,” “Abbreviated terms should have been explained” and “Time was too tight for the content.” The fact that this kind of adverse reactions were returned is understandable considering all participants were from non-VCCI member companies. So a lesson learned in this seminar is that it is necessary to grasp the knowledge 16

level of seminar participants and adjust the content appropriately beforehand. Also it should be noted that questions kept coming afterwards as well. This fact implies that interest level of audience was not necessarily low. Since 2006 VCCI has steadily run similar seminars at prefectural technology centers in Japan as an outreach program. It is VCCI’s intention to continue this program by catching needs and adjusting level of presentation to participants in the future.

Lastly we like to express our sincere gratitude to people of the Tottori Institute of Industrial Technology for their kind cooperation.

Report on Attendance to Meetings of R&TTE-CA and EUANB By Steering Committee

Foreword R&TTE CA is an association organized by conformity assessment bodies and some manufacturers operating basically in Europe which are interested in R&TTE Directives (on radio equipment and communication equipment). They deal with technical matters ranging from conformity schemes, radio communication technology to measurement techniques. They regularly meet twice a year for discussion. The purpose of our visit to this meeting was to build cooperative relationship with accreditation bodies and testing laboratories in Europe while getting acquaintance with European engineers on one hand and to get VCCI known better by them on the other hand. We also attended a meeting of EUANB (EU Association Notified Bodies), a conference body for EMC certification machineries.

The 27th R&TTE CA meeting Date and time:

November 27, 2013

9:00 – 17:00hr.

Place:

Q and A throughout the day

All speakers

The symposium was started with greeting by Mr. Satake. 

He talked about (1) merits for VCCI members and (2) changes to the Rules of Voluntary Control Measures



AS to (1), he pointed out that easy export of products is made possible based on mutual recognition of conformity data with overseas partners, and as to (2), VCCI members can accumulate technical know-how for fostering their engineers and they can stay abreast of the most recent regulatory information



As to mutual recognition of conformity data it was made possible since 2007 when Japan and US closed MRA. Mr. Satake elaborated relations of parties involved in the MRA both in Japan and the US which enabled mutual recognition of conformity data.



As to self verification of conformity, VCCI opened the requirements measurement facilities should meet including 3-meter method. Merits of this scheme is that manufactures can enjoy streamlined operations, reduction of cost and fostering engineers



In terms of accumulation of technical know-how and fostering engineers, the guideline for telecommunication ports conducted EMI measurement, contribution to CISPR of VHF-LISN and paper contribution to various symposium are picked up as examples



Mr. Satake stressed that VCCI members enjoy getting updated with movement in the world on EMC regulations through VCCI international forum, EMC seminars at prefecture industrial technology centers and in technical seminars like this one.



One of changes to VCCI rules in 2014 will be that members are allowed to indicate VCCI mark not only on the products themselves but also on packages and cartons of the products. Mr. Satake explained allowable way of display and banned way of display.

Next, Mr. Hoshi, Chair of Technical Subcommittee presented items in VCCI Technical Requirements and measurement facility registration to be revised in the coming fiscal year as follows.

VCCI Dayori No.112

2014.4

23



Transfer impedance of current probe is changed to meet MIC endorsement of CISPR standard with refinement



Flow chart to guide the selection of measurement method for telecommunication conducted EMI (Appendix IV of Technical Requirements) is refined by including the case where the member intends to interchangeably connect different cables to a given port.



Clarified Svswr referenced position for measurement (Appendix IV of Technical Requirements)



Revised the flow chart on required condition for Svswr measurement position in the case test volume size is smaller than 1.5m so the number of test positions is not limited to one



Make site validation cycle for NSA and VSWR compatible with that of calibration and inspection which is 12 months (now it is 6 months, Normative Annex 2)



As supplemental information VCCI’s organized session in EMC ‘14/Tokyo (May 13 – 15, 2014) was introduced to encourage members’ attendance.

Revision of Normative Anne 3, “The rules for market sampling test,” by Mr. Kanno, Chairman of market sampling test subcommittee 

Change the priority of actions to be taken by the member in case of Failed-tentative



Information to be disclosed for the case of “Failed” will include the name of OEM supplier, if involved.



Sampling inspection by document will include measurement method to pursue strictness



Make the flow chart on appraisal procedure more lucid

Mr. Osabe as the leader of CISPR32 WG presented the status on the activities of his group kicked off this year under the VCCI Technical Subcommittee and the status on the deliberation in CISPR 32 Ad Hoc Group in the MIC Radio Wave Utilization Environment Committee (MIC AHG on CISPR32 in short) 

MIC AHG on CISPR32 formulated in June 2013 initially with 15 members with terms of reference to create MIC endorsed CISPR 32 Ed. 1 and Ed. 2 including ongoing CDVs with local refinement by June 2015



New VCCI Technical Requirements based on the MIC endorsed CISPR 32 will be presented to VCCI Technical Subcommittee by March 2015



Gave a detailed explanation on CISPR 32 and its difference from the current VCCI Technical Requirements (on limits, operational conditions, measurement facility, testing arrangement and measurement method)



Items to study for the development of new VCCI Technical Requirements include EUT test volume for 3m method, application of measurement uncertainty to conformity assessment, testing by FAR if CDV on the subject is approved and weighing testing reproducibility. Responsible working groups are already tackling with those problems.

The following Q&A took place after the presentation by Mr. Osabe Q1: I think it is good that the flow chart to determine measurement method will clarify conditions for the selection of UTP and STP, but I would like you to propose such conditions to CISPR in consideration or harmonization with the international standards. A1: I believe interpretation of the selection of measurement method by members is unmistakably described based on MIC refinement. Q2: Which do you mean by the external power supply unit, the edge of AC adapter or the edge of equipment? Also in an arrangement in which vertical metal reference plane is used and the length of AC cable is too short is it acceptable to connect extension cable? A2: It is 80cm from the edge of AC adapter. Also if AC cable is too short, use extension cable. We will consider the addition of figure Q3: This is about VCCI mark indication on other than the equipment and operation manual. Do you mean it is allowed even for non Class B product? A3: Displaying VCCI mark as a symbol in other than operation manual will become allowed Q4: One of the items on which CISPR 32 does not agree with the current VCCI Technical Requirements is that the use of test patterns other than H pattern is allowed as display signal. The idea itself is not bad but I am concerned that H pattern gave out noisier emission, so I like to use complexity degree 3 or 4. A4: We need to watch direction in CISPR 32 Ed.2 in terms of CDV.

Next, presentations by each working group under the VCCI Technical Subcommittee followed starting with CISPR Project WG. Leader Mr. Mizutani talked about deliberation in CISPR/SC-A, SC-I and Ottawa meeting as follows. 

The CISPR Project WG under VCCI Technical Subcommittee participates in Japanese miller WGs to CISPR/SC-I, SC-A and CISPR miller committee



In terms of SC-A related subjects, requirements for measurement receiver using external amplifier and calibration of EMI measurement antenna among others are on the table of deliberation. In terms of SC-I related items, CISPR 35 and five CDVs on CISPR 32 are being discussed



Topics and resolutions of CISPR Ottawa meeting held in October 2013  TFs were established in WG2 (1) on testing method for multimedia equipment with wireless power

transmission capability and (2) to study the inclusion of game machines in the scope of CISPR 32  Mr. Osabe delivered an interim report on the international round robin test on the control of

terminating condition of EUT power cable in SC-I/WG2. He is expected to prepare the final report on the project by the next SC-I/WG2 meeting in Hong Kong.  A report was given on the influence of material of EUT table to GHz range measurement. Even

Styrofoam painted for structural reinforcement influence the result of measurement above 6GHz

Mr. Makimoto, a member of Radiated EMI measurement WG, made a presentation on the following topics

VCCI Dayori No.112

2014.4

25

among others 

VCCI requires that the diameter of the outer circumference of the test volume must be smaller than

2 m in measurement at distance 3m while the size of the test volume must be within the test volume validated in NSA testing site according to CISPR 32. This means that the size of test volume can be larger if CISPR 32 is followed. This study was to revalidate of the size of the test volume in measurement distance 3m 

Parameters to take into consideration for the study of the relationship between test volume and measurement distance include receive antenna beam width, type of receive antenna, attenuation by distance in the case of multiple signal sources are involved in the transmitter, difference in EUT beam width, measurement distance and difference between NSA evaluation and real machine measurement.



Experiments confirmed the influence of antenna directivity and difference in directivity between horizontal and vertical polarization. These were also confirmed by azimuth patterns. Throughout these findings it was proven that measurement deviation is kept small with the 3m method of VCCI Technical Requirements



Follow-on studies will include investigations of test volume by taking antenna characteristics (beam width) into consideration and the verification of test volume with real machines

The leader Mr. Akiyama of Conducted EMI measurement WG presented the following two topics 

On the extension of “The study of grounding condition for AMN placed on a table 40m high from horizontal metal reference plane based on CISPR16-2-1:2008 using real equipment” of the last year, this year the WG extended the study to measurement with network analyzer. Conclusion was that measurement depends on the width of grounding conductor and kind of AMN, so it is not recommendable to do measurement in this setup.



Compared results of measurement of 2-wire telecommunication port done via transformer coupled ISN and via resistance division type ISN. Resulted difference is 3 – 4 dB at most, so it was concluded that use of transformer coupled ISN (8-wire) for 2-wire telecommunication port is acceptable.

Next, Leader Mr. Makino of “Antennal calibration working group” presented the purpose of establishment of his working group and talked about the analysis of problems with using broadband antenna with 3m method 

Key words of study by the “Antenna calibration working group” include effects of using hybrid antenna for short distance, radiated patterns, impedance, effects of cross-polarization, factors leading to error in calibration and NSA measurement and antenna calibration under the free space condition to name a few



VCCI issued a note that in using hybrid antenna with 3m method, exercise care in using it for the final test. So the WG compared (1) measurement using hybrid antenna against (2) measurement using bi-conical antenna/(3) log periodic antenna to know the degree of difference. The result was, the difference between (1) and (2) was±3.0dB and between (1) and (3) was±2.0dB

26

VCCI Dayori No.112

2014.4



In summary the experiment report concluded that further study is needed on cross-polarization characteristics and factor correction condition with SSM method as well as EUT radiation patterns

As the last presentation in this technical symposium Mr. Osabe, the leader of VHF-LISN Working Group, presented “Interim report on VHF-LISN International Round Robin Test – Study of inter-laboratory correlations by way of controlling terminating condition of EUT’s mains port” together with what was deliberated in SC-1/WG2 of CISPR Ottwa meeting on the subject 

The international RRT, being participated by 18 sites of 10 countries/5 continents, started out with Australia will end in February 2014  Reported in the Ottawa meeting as an interim results was that 14 sites of 11 countries were finished by

year end 2013  Standard deviation between sites in the measurement of comb generator is largely improved by using

any of VHF-LISN, CMAD and CDNE compared to the measurement without those devices. In the measurement of tower PC, VHF-LISN and CDNE (balanced and unbalanced) showed improvement like in the case of measurement of comb generator, but improvement by CMAD was marginal  The RRT will be completed by mid February 2014 when the comparative measurement in laboratories

in Denmark, Sweden and China will have been completed  Based on the result of the RRT Leader Osabe will prepare a proposal on VHF-LISN to be included in

section 6.3 of CISPR32. The technical symposium was adjourned with a message by the moderator that any additional question can be made online by just clicking “contact” button in the VCCI Website.

Before putting down a pen Number play Do you know a play to produce digit “10” from 4 numbers of automobile license plate, serial number of tickets or some such numbers through the four fundamental operations of arithmetic? Recently a TV commercial presents difficult problems of this play as some of you may know. This play, called “10 puzzle” or “Make 10,” is good for killing your time or training your brain. When I need to kill a longer time like while travelling with Shinkansen bullet train or airlines “Make 10” leaves much to be desired in terms of time I can kill with. So I indulge in Sudoku instead. As many of you may know the rule of Sudoku is as follows. It uses a grid of nine by nine squares or cells that are subdivided into nine subgrids of three by three cells. The objective of Sudoku is to enter a digit from 1 through 9 in each cell in such a way that each horizontal row, each vertical column and each subgrid contains each digit exactly once. Last year Sudoko was included in entrance examination

of a private university, which became a talk of town among some Sudoku manias. I indulge myself for this puzzle as I am captivated by solving process using strategies like X-Y Wing and Skyscraper and I feel great when I was able to solve a super difficult problem. Turning to our daily work there is no established solving techniques like Sudoku for almost all real problems. So our pleasure will get greater if solving them with unique solutions we find ourselves. It is obvious that you need to cultivate your skill and power to get deeply moved by the fruit of success, so maybe I should not kill my precious travelling time by playing with numbers. Back to “Make 10” referred to at the outset I have heard that there is a rule that say combinations of four numbers except “0” are solvable without fail. So here is a problem for you the reader. Please make 10 from “3478.” If you can solve this problem within 5 minutes you are a flexible thinker. Why don’t you challenge it? (I.H)
