Development of Analog Filtering Circuit for Electromyography Signals

摘要

Filtering is an integral part of any process associated with acquisition or processing signals. Electromyography signals are complex signals consisting of multiple interfering components. Large amount of noises and interferences influence on the signal in the acquisition process. In this regard, obtaining a real signal without noise is a very important task. EMG signal filtering circuit was simulated and developed in this paper. This circuit satisfies the necessary requirements and can delete the noises which appeared by signal non stability and movement artifacts.
