摘要:

AbstractThe purpose of this paper is to give a sufficient condition for the uniqueness of the steady state for circuits that are composed of strictly locally passive capacitors and inductors, of time‐dependent bounded voltage and current sources and of a resistive N‐port that is strictly locally passive and eventually strictly passive. It is an extension of previously obtained results by the same authors, where strong local passivity was required. the new condition allows one to give a bound on the source amplitudes below which passive elements. It also gives a more explicit content to a theorem by Chua and Green which states that for sufficiently small source amplitudes the steady state is unique. the new condition is obtained by giving explicit uniform eventual bounds on the solutions ast→ ∞, which are of independent interest. Two examples illustrate that the various explicit bounds can easily be computed in concrete e

摘要:

AbstractA number of new elements for switched‐capacitor filters based on voltage inverter switches will be described. the new circuits simulate elements which are obtained from the normally used ones by FDNR transformation. They are insensitive to bottom plate parasitics and the influence of the to plate parasitics can be reduced. No matching is required between any capacitors in the SC circuit, so that the same low sensitivity to element variation holds as for the reference structure. These new elements allow realization of some further filter structure

摘要:

AbstractIn this paper some issues concerning the design and implementation of a satellite transponder's channelizing filter of degree 6 are discussed. In particular, the construction of the transmission coefficient, the synthesis procedure and the realization are discussed. the amplitude and the group delay responses of the filter are optimized simultaneously to meet prescribed requirements. the prototype filter has been synthesized as a cross‐coupled array. Explicit formulae for the element values in terms of the real and the imaginary parts of the poles of the transmission coefficient are derived. Single mode direct coupled cavity realization with positive and negative couplings has been developed. an experimental filter has been constructed, the measured responses are very close to the computed one

摘要:

AbstractDiscrete scattering Hurwitz polynomials play for discrete systems a similar role as scattering Hurwitz polynomials do for classical systems. A number of properties of discrete scattering Hurwitz polynomials are presented. These properties are obtained by deriving them from the corresponding properties of scattering Hurwitz polynomials. This is achieved by considering polynomials associated in a proper way to given polynomials and by examining the nature of the corresponding transformations.

摘要:

AbstractA review is made of recent developments to the simultaneous lowpass approximation problem of amplitude, phase and delay. the closed from solutions (reciprocal and non‐reciprocal) are expressed in terms of the arbitrary phase and delay polynomials (APD

摘要:

AbstractThe Brune and Darlington syntheses for one‐ports have been extended to n‐ports by several authors. the synthesis algorithms are well established and are not discussed in this paper, which is essentially concerned with the minimal realizations (in the total number of elements, including ideal transformers) of the 2n‐ports occurring as building‐blocks in the synthesis. A unified view of that subject is presented, including many new results and a critical survey of the literature. an appendix dealing with the contragradient reduction of a pair of rectangular matrices is of independent algebraic i
