摘要

A technique for the design of recursive digital filters is presented which leads to a compromise between phase and amplitude response in one design step. The computational method is derived in the time domain and is based on solving a system of equations by least squares techniques. The method may be denoted as comparatively simple. It is shown that without major complications the technique may be extended to the design differentiating and integrating filter algorithms, where the systematic design of numerical integration formulas should be of great interest. Several examples are given to demonstrate how the presented technique may be applied usefully. Particular emphasis is laid on cases which are of interest in the control and simulation of dynamical systems.
