Evaluation of Frequency Domain Features for Myopathic EMG Signals in Mat Lab

摘要

The proposed EMG signals analysis relies on the frequency do main where features of healthy EMG signal and myopathic EMG signals are analyzed and compared . Methodology described the relationship between the EMG signals and the properties of a contracting & myopathic muscle b y analysing its power density spectrum. Periodogram Mean-Square Spectrum Estimate (PMSSE) of EMG Signal and t he Power spectral Density is calculated with Welch's PSD estimate method by taking Hamming & Kaiser Window for both the healthy & myopathic signals. The analysis can provide important clues to design feature extraction methods and the resulting information can be used to determine the origin of the weakness
