... used for updating the filter coefficients that enjoy fast adaptation. In addition, a new algorithm using adaptive filtering with averaging (AFA) is also verified. The main advantages of AFA algorithm ... in forming effective algorithm for rejection noise. The algorithm embodies fast adapting capability, as sharp change in angle grinder noise characteristics is noticed. Usi...
