Abstract(in English) | In this paper, we proposed an adaptive notch filter using an allpass filter for the elimination of multiple unknown narrow-band signal or the sine waves imbedded in abroad-band signal. The adaptive algorithm is based on the steepest descent method and the updating value of the algorithm is the correlation of the input signal to the weights of the forward part of the allpass filter and the estimation error. It is proven that the weights after converging completely suppress the narrow-band signal when assuming that the broad-band signal and the narrow-band signal are statistically independent. Finally, the convergence performance of the estimation accuracy and the weights are verified by the computer simulation. |
