| Abstract(in English) | Adaptive digital notch filter which eliminates unknown sinusoids from a wide band signal, and which is realized as a cascade of a second order allpass filter has already been proposed. In this paper we propose a new algorithm for this kind of adaptive digital notch filter. The frequency estimate of the proposed method has a reduced bias in comparison with the conventional method. We explain the reason for the reduction in the bias using theoretical analysis. This result is also verified from the computer simulation results. |
