A low-cost, multi-channel, EMG signal processing amplifier.
There is a growing need in studies of movement control to expand the number of muscles from which EMG activity is recorded during performance of motor tasks. Optimal viewing and analysis of this EMG activity requires signal processing which provides adjustable gain and baseline offset as wells as selectable AC coupling, rectification and filtering. This paper presents a low-cost circuit that combines two channels of EMG signal processing capability in one module.
