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.
