EMG FILTERING SYSTEM USING SWITCHED CAPACITOR MF10 AND ACTIVE FILTER UAF42 INTEGRATED CIRCUITS

Abstract

This paper presents an Electromyography data filtering system with integrated circuits with switched capacitor MF10 and universal active UAF42 filters. The filters constructed are a Low Pass with cutoff frequency of 500Hz and Band Stop with cutoff central 60Hz employing components with commercial values. Its purpose is to show what are the major characteristics and functions for the construction of a system to filtering EMG signals for use in robotic applications. For analysis, the system is tested and compared with a surface Electromyography data acquisition with filters constructed by operational amplifiers. The results exhibit a good performance for the desired application.
