| Abstract(in English) | Adaptive infinite impulse-response (IIR) notch filters have been applied in a lot of fields such as digital communications, biomedical engineering, control etc. In this report, we first simplify a variable step-size plain gradient (VSS-PG) algorithm developed for the second-order adaptive IIR notch filter with constrained poles and zeros, and then present in depth performance analysis. Difference equations for the estimation error and the mean square error (MSE) of the filter coefficient, the VSS and its square value are derived. Furthermore, closed-form expressions for the steady-state properties of the algorithm are also developed. Extensive simulations are performed to confirm the effectiveness of the simplified VSS-PG algorithm as well as the validity of the analytical findings. |
