摘要: The paper presents a method for designing 2-D IIR filters with quadrantally symmetric magnitude response. is based on two error criteria, i.e., equiripple criterion in the passband and least-squared stopband. Two objective functions are introduced filter design problem transformed into an equivalent bicriterion optimization problem. stability of ensured by explicitly including constraints considered A two-step solution procedure proposed. In first step, genetic algorithm applied. final point from used as starting local method. examples given to illustrate proposed technique. comparison designed using LS approach also presented.
