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 method can be directly used for both even and odd degree filters, and yields simple explicit expressions for the filter coefficients.

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

Design methods for one-dimensional FIR digital filters can be separated into equiripple optimal approximations such as the Remez algorithm, and weighted least-square methods where the weight function is combined with the simple square error in the algorithm. For two-dimensional FIR digital filters,
