Abstract :

There are many methods available for filter designing. But problem arises when one has to find an optimal solution between two contradictory parameters, for example step response of filter should have minimum settling time and frequency response of filter should also have to satisfy constraints. There are many papers published on the GA based filter design, but those researches only include one parameter for optimization. In this paper we have shown the two objective fitness functions and found Paratoo Optimal Solution between those objectives. we have designed a low pass filter with the multi-objective GA technique and considered cutoff frequency and damping as objectives by which we have found the optimal coefficient of the IIR low-pass filter(b and a) and found desired step and frequency response.
