Adaptive IIR notch filter using a modified sign algorithm
DOI:10.1016/j.sigpro.2008.08.002.png)
Abstract
En 中文
Modified sign algorithm (MSA) for a second-order constrained adaptive IIR notch filter (ANF) is proposed and analyzed in this paper. Difference equations for the convergence in the mean and of the mean square, and steady-state estimation Was and MSE are derived in closed form. Moreover, a coarse stability for the MSA is carried out. computer simulations are conducted to corroborate the theoretical analysis. (C) 2008 Elsevier B.V. All rights reserved.
