l_p approximation of the group delay response of one- and two-dimensional filters

An algorithm is developed to design all-pass filters that best approximate in the l_{p} , sense a prescribed group delay response. This algorithm can be used for both the cases of one- and two-dimensional filters. To illustrate the method, several examples for designing one- and two-dimensional filters are solved.
