Adaptive notch filters (ANF) are a special case of IIR adaptive filters that are able to track and cancel a time-varying sinusoid or a narrow band interference signal from a broad band signal. These filters update zeros and poles of the notch filters based on an objective function that minimizes the output signal energy. An ANF algorithm can only be used in practical applications if the underlying...
