The design of infinite impulse response (IIR) filter has increased attention in the field of signal processing inrecent years. This paper presents the design of Band Pass Butterworth and Chebyshev infinite impulse response (IIR)filters with requirement of less ripples in pass band and stop band and small transition width. The Different optimizationalgorithms are available in literature but the Genetic Algorithm (GA) has been used here for the design of Butterworthand Chebyshev infinite impulse response (IIR) filters due to its simplicity and ease of implementation. The GeneticAlgorithm (GA) is a general optimization algorithm, but it needs to be modified to design a digital IIR filter design. Thesemodifications include a method for mapping a filter to an element, evaluation of the fitness function of the IIR filter,creation of an initial population of the IIR filter. The Genetic Algorithm is applied in order t o obtain the designedmagnitude response (Hn) as close as possible to desired magnitude response (Hd) .The proposed Algorithm has beentested for band pass Butterworth and Chebyshev IIR filter design problems.
