    The author was asked to speak on the subject of "EMC (electromagnetic compatibility) twenty years ago." He has organized his talk on three general areas: 1) organizations, 2) specifications and standards, and 3) measuring instruments. Initial efforts toward organizing a group on radio frequency interference (RFI) are recounted. Then the development of specifications and standards, including the fi... View full abstract»

    A battery-powered optical telemetry transmitter, 2.5 X 2.5 X 3 cm, has been developed for use with various electromagneticfield hazard probes. The electrical outputs from one of these probes, containing three orthogonal sensors, are electrooptically converted to three separate optical pulse trains so that a dc to 2-kHz information bandwidth is established in the transmitter using frequency-modulat...

    The electromagnetic surface wave which can propagate over a rectangular wire mesh of infinite extent is considered. The propagaton constant is determined both from a rigorous Floquet formulation and an approximate method using averaged boundary conditions. The agreement is fairly good for sufflciently small mesh dimensions. The rectangular mesh is found to be highly anisotropic, and the possibilit... View full abstract»

  • On Electromagnetic-Field Excitation of Unshielded Multiconductor Cables

    Publication Year: 1978, Page(s):495 - 500
    Cited by:  Papers (9)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (913 KB)

    Unshielded multiconductor cables are considered to be iliuminated by electromagetic plane-wave fields. A study of the currents that are induced in the terminations is made using quasistatic circuit theory, transmission line theory, and wire antenna theory. Questions of accuracy, ranges of validity, and general trends are addressed. View full abstract»

  • Radio Signals with Large Relative Bandwidth for Over-the-Horizon Radar and Spread-Spectrum Communications

    Publication Year: 1978, Page(s):501 - 512
    Cited by:  Papers (4)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2129 KB)

    It is known that radio signals must have a small relative frequency bandwidth if structures and circuits resonating with sinusoidal functions are to be used for radiation and reception. This paper develops concepts showing that a small relative frequency bandwidth is also required for the use of amplitude or frequency modulation of sinusoidal radio carriers in the usual form. However, it is easy t... View full abstract»

  • A Comparison of Test and Model-Predicted RF-Pulse Susceptibilities of UHF Transistors

    Publication Year: 1978, Page(s):513 - 514

    A semiconductor thermal-damage model was presented previously. Accuracy verification was limited to dc pulses and a damped sinusoidal waveform. Data published on UHF transistors allow additional model verification to RF pulses. 1 Results confirm that dc-pulse data are sufficient to predict RF-pulse damage levels. View full abstract»

  • A Simplified Computational Technique for Longitudinal H-Field Shielding

    Publication Year: 1978, Page(s):514 - 516
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (566 KB)

    A method is described for the calculation of the shielding effect of a set of coaxial circularly cylindrical tubes in an alternating longitudinal H-field. The arrangement is modelled using a nonuniform transmission-line equivalent circuit composed of a number of micro-T-circuits. The use of Bessel functions is completely obviated without loss of accuracy. View full abstract»

  • On the Walsh-Hadamard Transform and Prime Implicant Extraction

    The Walsh-Hadamard transform (WHT) provides a one-to-one mapping of n-variable Boolean functions onto an n-dimensional transform space. As such, it enables synthesis procedures to be carried out in the transform domain. This short paper discusses the role of the WHT in extracting prime implicants, which is pertinent to the overall minimization problem. First, a procedure to identify all the prime ...

  • On the Walsh Analysis of Nonlinear Systems

    Publication Year: 1978, Page(s):519 - 523

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (656 KB)

    This paper considers some aspects of the analysis of nonlinear systems via Walsh functions. Two basic approaches are investigated. These are 1) a characteristic-function method which assumes a Walsh-transformable nonlinearity and 2) a matrix method that is suitable when the input can be represented by a truncated Walsh series expansion. Illustrative examples are included. View full abstract»

    The author notes a degree of confusion as to the overall objective of spectrum management. The concepts of spectrum conservation, spectrum efficiency, and economic efficiency are discussed and compared. Economic efficiency is concluded to be the proper objective. View full abstract»
