Comparability of Power Spectral Density Estimation of EMG Signals Using Non-Parametric Methods

The purpose of this paper is to focus on the issue of EMG amplitude and spectral estimation with algorithms based on nonparametric methods. As EMG has many non parametric methods, we had a practical approach to consider a perfect signal with comparison of different models like Welch, Bartlett, Period gram and Blackman turkey method. The basic idea was taken to give a feedback process through which signal is best depending upon the terms of raw signal and smoothing signal.
