The proposed adaptive algorithm is for a second-order adaptive IIR notch filter based on gradient algorithm. The simulation results shown that the proposed algorithm provides fast convergence speed, and has low steady-state mean square error and low variance of filter coefficient....
A Novel Adaptive IIR Notch Filter for Frequency Estimation and Tracking Xiaobo Tan Institute of Communication Engineering PLA Univ. of Sc..
In this paper, a new class of a variable step-size algorithm for a second-order lattice form structure adaptive IIR notch filter for detection of sinusoids in noise environments is presented. The proposed algorithm is adjusting two variable coefficients of the adaptive IIR notch filter: one is ...

A New Algorithm for Howling Detection
Thus in this work, we present a generalized design framework for IIR multiple notch filters whereby we aim to: a) deduce an improved design process of the all-pass filter-based method, b) maximize the availability of phase information of all-pass filter, and c) introduce selection mechanisms...
