    Various methods based on optimization have been used to design linear phase filters. One such method has been to use a general-purpose optimization program to minimize some error criterion, a function of the filter coefficients and of the error between the specified and achieved gain responses. However, if this were to be used with arbitrary phase designs, the error criterion would have to be form... View full abstract»

  • A solution for component valuse of radio frequency interference filters for phase-controlled switching systems

    Publication Year: 1974, Page(s):652 - 656

    When applied to phase-controlled switching systems, the performance of simple radio-frequency interference filters is limited by circuit operating considerations. More complex filters can readily be designed using curves given in the paper. Their derivation and typical performance are described. View full abstract»

  • A new mathematical model to the physics of propagation

    While Green's functions provide a powerful analytical means of solving the wave equation, they do not give a very realistic description of the mechanism of propagation. Also the adaptation of Green's function techniques to numerical methods of solution is not easy. This paper introduces the assumption that propagation takes place in discrete steps, and it is shown that Huygens's principle then bec... View full abstract»

  • Characterization methods of Gunn oscillators

    Publication Year: 1974, Page(s):667 - 672

    Three measurement techniques for determining the large-signal characteristics of Gunn-diode oscillator networks are described and compared. These are the reflexion method, the transient method and the steady state oscillation method. It is shown that the technique adopted should depend on the type of device to be tested.

    A new class of monotonic passband low-pass filters, referred to as transitional Butterworth-Legendre (TBL) filters, is introduced. The closed form expressions of the characteristic functions of these filters depending on one variable parameter q are derived by generalization of the results previously obtained for Legendre sharp cut-off monotonic filters. The parameter q, the values of which are re... View full abstract»
