UNSPECIFIED. (1993) DIRECT DESIGN OF APPROXIMATELY LINEAR-PHASE (ALP) 2-D IIR DIGITAL-FILTERS. ELECTRONICS LETTERS, 29 (9). pp. 804-805. ISSN 0013-5194Full text not available from this repository.
A fast design method is presented for approximately linear phase (ALP) 2-D IIR digital filters composed of a parallel connection of two allpass subfilters. The technique exploits the fact that the filter transform function depends on the phase of each subfilter. A closed form expression is derived for the phase and the filler coefficients of each subfilter are obtained by solving a set of overdetermined linear simultaneous equations.
