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 New Algorithm for Howling Detection
摘要: A family of stochastic approximation variants of the Steiglitz-McBride identification scheme [1]-[3] is developed for adaptive IIR filtering. Parameter convergence is shown by computer simulation. An interesting phenomenon, global convergence regardless of local minima, is observed....
A complex adaptive Harmonic IIR notch filter is proposed for estimating and tracking the frequency of periodic complex signals in a noisy harmonic environment. The transfer function of the developed notch filter consists of cascaded first-order complex transfer functions whose notch frequencies are constr...
