Discussion on the Optimization Design of Feature Extraction Methods of the EMG Signal

This paper introduces a digital signal processor based system design, through the computer acquisition individuals EMG(Electromyographic)signal data to monitor the dynamic activity of muscles, and the estimation of normal and pathological conditions of the acquired data of the power spectrum. In the collection system, the input signal of the two differential amplifier signal preprocessing and obtain the EMG signal linear feature. Obtain electromyographic signal is then digitized, and transmitted to the computer analysis. The optimization system for detection and Analysis on the clinical diagnosis of human functional status and rehabilitation has important significance.
