摘要

In this paper, the lattice form realization of an adaptive IIR notch filter is investigated. The gradient lattice algorithms for eliminating sinusoidal interference from a broad-band signal are proposed. In our approach, the IIR filter is a cascade of the second-order all-pole and all-zero filters and the coefficients of the FIR section are adapted only. Computer simulation results show that the proposed algorithms have considerable potential in adaptive notch filter applications, especially when the input signal-to-noise ratio is low.
