Digital Multiple Notch Filter Design Based on Genetic Algorithm

Abstract: Digital multiple notch filters are applied to remove or suppress several narrow-band interference components simultaneously in a digital signal while preserve the other frequency components unchanged. A novel design method of an infinite impulse response (IIR) multiple notch filter is presented in this paper. It is based on genetic algorithm (GA) which is one of the very effective tools of optimization. Firstly, the rational system function of the notch filter is constructed and the optimized objects are deter… Show more

“…There are several approaches to the IIR multiple-notch filter design. [1][2][3][4][5][6][7][8][9] Realization of notch filter using cascaded second-order sections form structures inevitable leads to uncontrollable passband gains, 2,6 while iterative design methods based on utilization of convex optimization 3,4,9 or genetic algorithms 5 exhibit high complexity especially for a greater number of notch frequencies. All-pass-based IIR multiple-notch filter design methods first introduced in Pei and Tseng 1 transform the specifications of multiple-notch filter magnitude response into those of the phase response of a corresponding all-pass filter.…”
