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.
在运动控制研究中，越来越需要在执行运动任务期间增加记录肌电图（EMG）活动的肌肉数量。对这种EMG活动进行最佳观察和分析需要信号处理，该信号处理应提供可调节的增益和基线偏移以及可选的交流耦合、整流和滤波功能。本文介绍了一种低成本电路，该电路在一个模块中结合了两个通道的EMG信号处理能力。
