In this paper we present an alternative approach to the direct design of 1-D recursive digitalfilters satisfying prescribed magnitude specifications with or without constant group delay characteristic. This method uses an iterative method to calculate the coejkients of the$lter's transfer,function a

An eficient method is presented for the design of 2-D circular symmetric recursive digital filters satisfying prescribed magnitude and constant group-delay responses. The transfer function of this class of 2-D filters has a zero-phase non-separable numerator and separable denominator 2-variable poly
A new technique is given for designing two-dimensional quarter-plane recursive digital filters. These filters have low sensitivity in the passband. An implementation scheme using complex multipliers is also given for these filters.
Previous results concerning the stability qf 2-D digital jilters in the presence of simple nonessential singularities of the second kind are extended to a very broad class of jiinctions having second kind singularities on T', the distinguished boundary of the unit bidisk, where these singularities m
