All‐pole equiripple approximations to arbitrary functions of frequency

Abstract

The problem of determining a rational function whose magnitude characteristic approximates some arbitrary functions of frequency in an equiripple sense is discussed. A novel method that provides a rational all‐pole equiripple approximation to any arbitrary magnitude response in the frequency domain is described. The technique is applied to a typical example that serves to illustrate the effectiveness of the method.
