Basic theoretical considerations of communications with electromagnetic Walsh waves are presented. The spectra of unmodulated Walsh waves radiated from a small electric dipole are computed for ideal and trap ezoidal approximations to Walsh function excitation. A link analysis based upon matched filter detection of the radiated Walsh waves received in thermal noise is presented. It is shown that the current required on the radiating element is proportional to the square root of the bit rate-to-carrier sequency ratio.

We determine the different voltages, as the crosstalk, which could appear on a multi braided coaxial cable when a disturbing cur rent flows on the outer braid. We compare the shielding efficiency of a classical coaxial cable to the one of a multi-braided cable. In that case, we suppose that insulating layers are situated between the braids, theoretical results point out resonances which appear when the concentric transmission lines made by the different shields are short-circuited. Measu rements on a two layer shield confirm the pre sence of these resonances. In order to avoid them, a first solution consists in connecting the characteristic impedances to both ends of the successive lines made by two adjacent bra ids. An other mean to damp down the resonances is to replace the insulant between the braids by a dielectric having an appropriate conduc tivity. Theoretical results show that the mul ti-braided coaxial cable gives a best immunity to disturbances than a single braid, but the improvement depends on the total length of the line and on the working frequency band.

Control Technology in collaboration with the Royal Aircraft Establishment have developed range of active and passive suppressors suitable for airborne use. The work was undertaken to make available an approved range from which suppressors could be selected either for incorporation in new equipment to enable it to comply with the relevant procurement specification or for retrofitting existing aircraft systems. The design of the passivè suppressors is based largely on the work presented at the 1972 IEEE EMC Symposium in the paper "An Improved Design and Measurement of Attenuation Characteristics of RF Suppressors" by M L Jarvis. Initially, development was of suppressors having cut-off frequencies which would enable equipment to meet the conducted emission requirements of MIL-STD-461 and BS.3G.100. Both 28 V dc and 200 V 400 Hz ac versions have been produced with a variety of current ratings - up to 10A for the ac suppressors and up to 100A for the dc suppressors. Both "T" and "H" versions are available. Details will be given in the paper of a BASIC program to evaluate prototype suppressor designs for minimum voltage attenuation or for insertion loss.

This paper compares the electromagnetic compat ibility (EMC) characteristics of conventional and coaxial magnetrons used in radar transmitters. The characteristics of major concern in this comparison are, emission spectrum, spurious emission, pulse shape and frequency stability. The data presented were obtained under the Department of Defense spectrum signature program. Measurements were made in accordance with MIL-STD-449D, and were monitored by the Electro magnetic Compatibility Analysis Center, (ECAC). The equipments measured were the AN/FPS-6 B (2.7-2.9 GHz), and the AN/FPS-16 (5.4-5.9 GHz) radars, located at the U.S. Army Electronic Proving Ground (USAEPG), Fort Huachuca, Arizona. The measurements show a significant improvement in the emission characteristics of the transmitters when they are retrofitted with coaxial magnetrons. The emission spectrum envelope of the coaxial magnetron is about one half as wide as that of the conventional magnetron in the region of 0 to 50 dB below the carrier. Below this region, the emission envelope of the coaxial magnetron was 10 to 20 dB below that of the conven tional magnetron. The radiated output levels of the second and third harmonic of the coaxial magnetron used in the AN/FPS-6 B radar were approximately 30 dB lower (82 and 90 dB down respectively) than those from the conventional magentron. A spurious output at a level approximately 50 dB below the carrier was detected in the output emission of the coaxial magnetron used in the AN/FPS-16 radar. This spurious output was at a frequency 110-120 MHz above the carrier frequency and is attributed to in adequate suppression of an undesired mode in the cavity. Short term frequency stability of the two types of magnetrons tested was comparable. In a four hour test, after 15 minutes warm-up, a total variation of + 250 KC was detected. Measurements showed an increase in the rise and fall times of the detected R.F. pulse of the coaxial magnetrons over that of the conventional magnetrons. This is a result of the higher Q of the coaxial type magnetron which also accounts for the narrower spectrum measured. Several characteristics of the two types of mag netrons which relate directly and indirectly to EMC are discussed in the paper. Also discussed are factors which should be considered when planning for use of coaxial magnetrons in future systems.

Data reduction for formal engineering reports has always been a time consuming and tedious function. When performed by hand, data compilation usually results in plotting, computation and tabular listing errors. A mechan ical means of circumventing the task is desirable and would make available more time for analysis of the results along with a more accurate presentation. By using a computer in conjunction with an automatic data plotter, raw data from tests can be analyzed and presented more accurately and in far less time than by manual preparation. This paper dis cusses the required inputs and form of presentation using a computer program called EMCEP, which stands for Electro magnetic Compatibility Emissions Presentation. The pro gram analyzes and compiles the reduced raw data generated from testing. This paper presents a method which has been designed and proven to streamline the data reduction process and which is especially useful to engineers burdened with manually operated EMI measuring instruments, tight sched ules, and low budgets.
正式工程报告的数据简化一直是一项耗时且繁琐的功能。当手工进行数据编译时，通常会导致绘图、计算和表列错误。我们需要一种机械的方法来规避这项任务，这样可以有更多的时间来分析结果，同时也可以得到更准确的表述。通过将计算机与自动数据绘图仪结合使用，可以比人工准备更准确地分析和呈现测试的原始数据，而且所需的时间要短得多。本文用EMCEP (Electro - magnetic Compatibility emission presentation，电磁兼容发射表示)的计算机程序讨论了所需的输入和表示形式。该程序分析和编译从测试中生成的简化的原始数据。本文提出了一种经过设计和验证的简化数据简化过程的方法，对于那些需要手动操作电磁干扰测量仪器、时间紧迫和预算低的工程师来说，这种方法尤其有用。
