| 摘 要： | 介绍了一种表面肌电信号 (EMG)测试调理电路和信号处理的方法。表面EMG测量中最难处理的问题之一是工频(5 0Hz)干扰 ,它处在有效的肌电信号频带之中。针对表面EMG的测量特点设计了一种信号调理电路 ,使肌电信号和工频信号并行单独处理 ,避免了不加区分地采用工频陷波器 ,这一设计思想在实际的肌电信号检测时取得了较好的实验结果。

| Abstract: | A surface electromyography (EMG) detection and proce ss ing circuit is discussed. The surface EMG is usually disturbed by power frequenc y noise. In that cases, it is a problem, because the surface EMG is confused wit h power frequency noise. A processing circuit for the measurement of surface EMG is designed by using a parallel structure respectively for EMG signal processin g and power frequency noise processing. It can be avoided that a 50Hz trap filte r abused. The experimentation proved the developed circuit was effective. |
