摘要：
A cascaded second order adaptive notch filter using an allpass filter has been proposed. A gradient based algorithm for the adaptive notch filters are used. However, the performance of the adaptive notch filter is decreased due to disturbance which inputs into a tap input signal. In this paper, in order to solve the problem, an adaptive line enhancer which reduces the disturbance in a reference signal is introduced to the adaptive notch filter. Finally, computer simulation results are presented to confirm the convergence characteristics.
