Abstract : As digital filters are often specified in the frequency domain, a method of approximation is required that meets periodic magnitude and delay or phase specifications. The method developed here is of particular merit as it may be used for any type of frequency characteristic, e.g., as required for the equalization of communication channels. Existing non-recursive filter realization methods realize linear phase filters only, whereas this method can correct magnitude and subsequently the delay of a system function, realizing non-recursive, purely recursive or recursive filters.
