Design and implementation of a 2-D linear phase IIR filter using symbolic computation routines

Abstract

A fully automated algorithm for designing two-dimensional IIR recursive filters with an approximately linear phase has been developed. Complete separability of the magnitude and phase generating transfer functions is assumed. An extension of the Chebyshev filter design algorithm has been used to design the magnitude transfer function and a specifiable… (More)
