Özet

In this work, considering the solution of analog filter approximation problem, evolutionary algorithms are used to obtain nth order transfer functions. Coefficients of denominator polynomial of low pass analog filter are optimized and this process is carried out for three different orders of transfer functions. Simulation results show that error values obtained with evolutionary algorithms are less than that of traditional methods. The feasibility of the proposed method on circuit realization is investigated by designing passive and active analog filter circuits which realize 3rd order transfer function.
