Abstract

In this paper, a hybrid optimization for the design infinite impulse response (IIR) filter employing particle swarm optimization (PSO) and artificial bee colony (ABC) algorithm is presented. The design problem is formulated as a mean square error between desired response and ideal response. For the stability of filter, a lattice structure in design is utilized. A comparative study of performance of PSO and its different variants is also made which shows improved efficiency of hybrid method in the field of IIR filter design.
