    This paper is a pragmatic tutorial review of the cepstrum literature focusing on data processing. The power, complex, and phase cepstra are shown to be easily related to one another. Problems associated with phase unwrapping, linear phase components, spectrum notching, aliasing, oversampling, and extending the data sequence with zeros are discussed. The advantages and disadvantages of windowing th... View full abstract»

    A very general computer program is described that can be used for the synthesis of passive LC, active RC, and (infinite impulse response) digital filters. Although it operates in both batch and interactive modes, this discussion deals exclusively with the interactive mode, which is somewhat more general and very easy to use. Apart from offering superior accuracy and flexibility, this program offer... View full abstract»

  • Asymptotic theory of mode coupling in a space-time periodic medium—Part II: Unstable interactions

    Publication Year: 1977, Page(s):1459 - 1469

    A singular perturbation analysis of the coupling of plane electromagnetic waves in an unbounded medium having its permittivity modulated by a progressive sinusoidal wave is carried out for the waves progressing parallel to the modulation direction. The phase velocity of the wave modulation is greater than that of the electromagnetic waves in the unmodulated medium. The interactions of the fundamen... View full abstract»

    The paper provides a review of current research on microwave reflector antennas with particular regard to those antennas which produce pencil-beam radiation patterns. After a preliminary examination of microwave antennas of different types attention is focused on circularly symmetric antennas with axially symmetric feed systems. This class of antenna accounts for the largest number of applications... View full abstract»

  • On stability and realizability of derived FDNR networks

    Publication Year: 1977, Page(s):1507 - 1508

    A proof is given for the empirical fact that resistance-capacitance-supercapacitance networks, as well as superinductanceinductance-resistance networks are unconditionally stable. This is in spite of the second degree poles at zero and at infinity. Realizability conditions are given for a function of frequency to be the driving point immittance of such networks.

    Two schemes of simulating grounded inductors using a second generation current conveyor are reported. Both schemes provide simulated inductors that are relatively frequency independent, with suitable design, at moderately high-Q values. View full abstract»

  • Nonlinear behavior of the BARITT diode microwave oscillator

    Publication Year: 1977, Page(s):1512 - 1514
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (303 KB)

    Nonlinear behavior of the free-running BARITT diode oscillator has been observed. Discontinuous changes in oscillation frequency and output power occur as the bias current changes. These non-linearities have been investigated in coaxial and waveguide oscillators and are caused by device and circuit interactions. View full abstract»

  • Precise wide-dynamic range constant current ratio circuits

    Publication Year: 1977, Page(s):1514 - 1515
    Cited by:  Papers (4)  |  Patents (3)

    A method of compensation of unequal VBE's in a conventional constant current ratio circuit is proposed, which improves the accuracy and the dynamic range of the current ratio considerably, without the need to use any higher resistance than normally desirable for integrated circuits. The linearity of the current ratio is better than 1 percent over a dynamic range of greater than four ord... View full abstract»

  • Further comments on "An alternate derivation of the maximum likelihood estimate of a covariance matrix"

    Publication Year: 1977, Page(s):1515 - 1516

    The alternate derivation of the maximum likelihood estimate (MLE) of a covariance matrix, as offered by Nitzberg still contains certain problems, albeit his recent correspondence has assisted considerably in understanding the approach. A major point of difference centers around the last few steps of the alternate proof where a transition is attempted from the MLE of certain eigenvalues to the asso... View full abstract»
