## Abstract Two of the four central design problems for FIR filters in the frequency domain are the problems of simultaneous approximation of prescribed magnitude and phase responses and prescribed magnitude and group delay responses, respectively. In the past, these problems have almost always bee

The non-linear problem of simultaneous approximation of the magnitude and phase by an FIR digital filter is studied. Usually this problem is solved indirectly by solution of the complex Chebyshev approximation problem of the frequency response of the filter, which can be described as a linear or non

## Abstract The approximation of the finite‐impulse‐response (FIR) digital filters using the bilinear transformation of a restricted class of the rational functions is considered. The reference rational functions are constructed for maximally flat selective and quadrature filters. The proposed meth
