Abstract

The adaptive notch filter with N notch frequencies, which is constructed with N cascade second-order notch filters, is presented to estimate multiple frequencies. Parameters of each second-order notch filter are optimized concurrently with LMP (Least Mean P-power) algorithm. Simulation shows the method has good results in case of estimating single frequency, multiple frequencies and changing frequency under different signal-to-noise ratio, but the noise influences the estimation accuracy and rate to some extent, and the tracking effect is poor.
