Abstract: A novel design strategy of Butterworth IIR filter is proposed in this paper. It considers two most effective hybrid optimization techniques GA and BBO. The results show that GA and BBO based filter designer is able to find transfer function required for given magnitude response. The proposed algorithm doesn’t take unnecessary computation time and good in exploiting the solution as the solution doesn’t die at the end of each generation. Hence, the performance of proposed hybrid algorithm outcomes the performances of previous proposed algorithms for designing of a digital filter. The simulated results show that the design filter is highly stable and the filter gain is exactly same as that of the ideal filter. The magnitude of the filter is less than one (
