Computation of IIR Filter Coefficient using Genetic Algorithm

Abstract

In the proposed paper the filter coefficient of the infinite impulse response filter is estimated by using genetic algorithm. Genetic algorithm is a computational optimization technique which optimizes fitness function. The paper finds the optimum coefficient of the infinite impulse response filter and compares it to the filter coefficients obtained after conversion of analog filter into digital infinite impulse response filter. It is found that the coefficients obtained after genetic algorithm are more optimal.
