Development of analog filtering circuit for electromyography signal

Abstract

Filtering biophysical signals, such as electromyography signals very important task for the designer, who designs the biophysical signals acquisition systems. Many factors influence on the signal during acquisition process. Receiving the real signal proceeds in big noise quantity conditions. For receiving the real electromyography signal, it is necessary to delete the noise components from the signal. Filtering circuit for the EMG signal is developed and simulated in Filter Pro Desktop program. The resulting circuit responds the requirements. It allows to delete the noise from movement artifacts and signal instability.
