    A portable multichannel battery-operated measurement system was developed to measure the rms magnetic-field noise spectrum in the frequency range from 100 Hz to 375 kHz. During each measurement, the entire spectrum is measured simultaneously through the use of time-domain recordings which are later analyzed by Fast Fourier Transform (FFT) processing. Dynamic ranges of 60 dB in a 125-Hz bandwidth a... View full abstract»

    Measurements of the radio noise environment at high frequencies (HF) using the Fa and Vd noise parameters have been made during 1973 and 1974 at several radio receiving sites in Eastern Canada. From the results of these measurements, two criteria have been developed to rate the sites quantitatively as to degree of degradation by manmade radio noise. The results also indicate that the CCIR atmosphe... View full abstract»

    The electromagnetic susceptibility of 2N918 UHF transistors is investigated. A single RF pulse at 240 MHz was applied directly to the base terminal with the emitter terminal grounded. The incident RF pulse power required to cause a 50-percent failure rate is in the 28-38-W range for a 3-¿s pulse duration and in the 130-140-W range for a 0.3-¿s pulse duration. The data indicate that all three 2N9... View full abstract»

    This paper presents balanced circuit techniques for the reduction and cancellation of the dominating third-order intermodulation tion product generated by broad-band solid-state power amplifiers. These techniques are applicable to collocated transmitters where the interference enters through the output port of the transmitter. A rigorous derivation is presented to prove the validity of the intermo... View full abstract»

    The problem of a plane wave incident upon one or more long, parallel slots in an infinite plane screen is treated by the method of moments. A Galerkin's solution with triangular expansion and weighting functions is used. The complete solution for aperture fields, transmission coefficients, near and far fields is formulated and programmed. Arbitrary polarization and arbitrary angles of incidence ar...

    The penetration of an electromagnetic wave through an aperture in a cylindrical structure is investigated. By using the moment method, the electrical and magnetic fields in a cavity behind the aperture are determined as a function of frequency of the incident field. The accuracy of the numerical solution is established through tests of satisfaction of the boundary condition, edge condition, and co... View full abstract»

    Determining the behavior of a body such as an electromagnetic shield in a known impressed field is a fundamental problem of applied electromagnetic theory. For bodies whose shape does not conform to a separable coordinate system, numerical techniques such as the method of moments have been found particularly advantageous. While the application of the method of moments may appear straightforward, i... View full abstract»

  • The Sinc and Cosinc Transform

    Publication Year: 1977, Page(s):88 - 94
    Cited by:  Papers (3)

    A new transform, the sinc and cosinc transform, uses Walsh functions to obtain the Fourier transform. This technique converts a staircase approximation of a function to a set of sinc and cosinc terms in the frequency domain that is equivalent to the Fourier transform. The calculation is slower than the fast Fourier transform (FFT) but is devoid of aliasing. The interpolation and scaling in the fre... View full abstract»

  • On the Use of Tailored Return-Stroke Current Representations to Simplify the Analysis of Lightning Effects on Systems

    Considerable siniplification is possible in the analysis of the interaction between a lightning return-stroke current and a system by selecting a return-stroke current representation whose Laplace transform has the same general form as the transform of the system transfer function.

    Two results are derived in connection with the "rustybolt" effect of signal distortion at a circuit element with a nonlinear current-voltage characteristic. A general expression is found for the effect of crossmodulation between two signals and also a formula providing information about the current-voltage characteristic from its harmonic generation properties. This latter result may be used to de... View full abstract»
