A novel notch filter using wavelet tranform and statistical curve fitting

A filtering technique based on wavelet transform and statistical curve fitting is proposed in this paper, to denoise the notches from the variable frequency non stationary synchronizing signal. Rapid processing of the proposed filter in the detection of the notches and removing them from the signal is justified by the results obtained from MATLAB/Simulink. Further, an experimental study is carried out to validate the performance of the proposed filter on a real-time signal.
