Abstract

This paper presents the algorithm for adjusting bandwidth of second-order adaptive IIR notch filter with constrained poles and zeros that works with the plain gradient algorithm to adjust its coefficient. The proposed method can increase the speed of convergence of the filter, especially, when the optimum solution is far away from the initial value of adjustment.
