Abstract :
The authors analyze the convergence of several adaptive notch filter algorithms for sine waves in colored noise, which were recently proposed in the literature. After pointing out the previous algorithms´ potential convergence problems, an algorithm is proposed for this problem that does not have convergence problems and provides accurate estimation results
