The adaptive notch filter that is composed of the adaptive transversal filter has the defect of the bias error caused by the broadband signal included in the input signal. In this paper we propose an adaptive notch filter with a few bias error using the new adaptive algorithm of SSCF-DP (Square Sum of Correlation Function with Decorrelation Parameter). The cost function of SSCF-DP algorithm is a square sum of the cross-correlation coefficient of the input and output error signal with decorrelation parameter. The analytical results and the above mentioned feature are verified by computer simulation.
