Real-Time Frequency Tracking Using Novel Adaptive Harmonic IIR Notch Filter

In this paper, we propose a simple and effective algorithm for frequency estimation and tracking under a harmonic frequency environment. The proposed filter structure contains only one adaptive coefficient and is very efficient for tracking the fundamental frequency of the periodical signal. Index terms Adaptive IIR Notch filter, harmonics, frequency estimation
