摘要:

AbstractA new algorithm is proposed to realize a digital transfer function. The final realization is in the form of cascaded lattice two‐pairs with the right‐most two‐pair being constrained such that one of its output terminals is connected directly to an input terminal. The complete realization usesmdelays, 2m+ 1 multipliers and 2mtwo‐input adders wheremis the order of the transfer function. Several special cases are included, along with an example illustrating the general al

摘要:

AbstractStatistical multiparameter sensitivity proposed by Rosenblum and Ghausi, for transfer function of a linear system, has been studied with regard to gain and phase sensitivities. It is shown that for small element changes a very simple relationship exists between these quantities. The integrand of these sensitivities are furthermore equivalent to the variance of magnitude and phase variations. Finally general formulas are derived which would simplify calculations for gain, phase as well as the transfer function. These formulas are helpful in optimization and comparison of various low sensitivity networks.

摘要:

AbstractState models based on graph‐theoretical concepts are presented for the computer‐aided analysis of large‐scale linear networks by decomposition in time as well as frequency domains. Several examples are analysed which illustrate the validity and efficiency of these models. These models exploit the sparsity and the repetitive structure present in most large‐scale n

摘要:

AbstractThis paper presents an application of the theory of thedegree of a mapto the study of the existence of solutions and some related problems for resistive nonlinear networks. Many well‐known results in this area have been generalized to allowcouplingamong the nonlinear resistors. The usual hypothesis requiring the nonlinear resistors to be eventually increasing has been weakened considerably by only requiring the resistors to beeventually passive. Instead of investigating special cases by special techniques, we study the network equations from a geometrical point of view. The concept ofhomotopy of odd fieldsprovides a unified yet simple approach for analyzing a large class of practical nonlinear networks. Many known results belong to this category and are derived as special cases of our generalized theorems. This approach leads to a much better understanding of the geometric structure of the vector fields associated with the network equations. As a result, in so far as the existence of solutions is concerned, the concept of eventual passivity is shown to be far more basic than that of eventual increasingness. The emphasis of the concept of eventual passivity also leads naturally to the inclusion of coupling among the nonlinear resistors.The homotopy of odd fields also provides some useful techniques for locating the solutions. Along this line, we also study the bounding region of solutions and discuss the operating range of nonlinear resistor

摘要:

AbstractThe systems to be considered consist of linear and nonlinear elements and are driven bya prioriknown periodic signals (carriers). The present theory deals with small perturbations from the periodic steady state. Use has been made of the ‘amplitude‐phase’ representation of the perturbations. The operator (jω0+ λ) is used, in which jω0indicates the time differentiation of the carrier components and the operator λ ( = d/dt) affects the perturbation only. The perturbations will be related by a ‘sensitivity’ matrixH. In order to illustrate the applicability of this theory, the performance of the dynamic limiter of Zaalberg van Zelst wi

摘要:

AbstractThis paper presents the theory and a time domain synthesis procedure for a class of orthogonal digital filters. These filters are derived from discrete Laguerre polynomials and in the case of exact representation possess an infinitely long structure whilst exhibiting an infinite impulse response.In practice the desired impulse response of a filter to be synthesized is truncated in time whilst speed and economic considerations impose a constraint on its length. By the nature of these filters, very few stages usually suffice to yield excellent fidelity in most practical cases. The filters, whose cascaded stages are eminently suited to multiplexing, are inherently stable.A computer‐aided design algorithm using a Fibonacci search algorithm is presented for optimizing the practical case having finite length and span. Two examples illustrate the procedur

摘要:

AbstractA simplified method—based on the concept of reflection filters—is presented for designing linear phase filters with arbitrary amplitude to phase constraints. This method starts with transfer functions with 2: 1 amplitude to phase constraints, and through varying the recurrence relation of the polynomials involved, transfer functions with more selective amplitude are obtai
