Abstract
This paper proposes a comb filter with adaptive notch bandwidth. The comb filter is used to reduce a periodic noise from an observed signal. To extract the desired signal completely, we should appropriately design the notch bandwidth of the comb filter. Specifically, we should design the notch bandwidth to be equal to the fluctuation bandwidth. In this paper, to automatically reduce only the periodic noise with the frequency fluctuation, we propose the comb filter which achieves the adaptive notch bandwidth. Simulation results show the effectiveness of the proposed comb filter.
