A new method for the computation of digital filter coefficients — Part I

Abstract

A new method tor computing the coefficients ot a digital algorithm to simulate a continuous transfer function is shown in a number of examples to be simple to apply and highly effec tive in operation. The poles of the function of s are mapped directly into the z-plane, but the positions of the z-plane zeros (which may be equal in number to the poles, or greater) are derived by a more complex process involving the use of the Taylor series expansion.
