| 摘 要： | 通过观察肌电信号(EMG)可以判断肌肉功能是否正常,这对利用A型肉毒毒素治疗肌肉痉挛性疾病十分有意义。EMG属于生物电范畴,信号微弱,并且易受干扰,针对EMG的特点设计信号调理电路。该电路采用两级隔离放大并经过滤波处理来提取肌电信号。对信号处理电路的特性分析表明,文中所设计的电路可以有效提取10～500Hz的肌电信号,并有效抑制工频干扰,因此该电路将在实际应用中取得较理想结果。

| Abstract: | We can determine whether the normal muscle function by observing the electromyography （EMG） ,and it is very important for us to cure the spastic diseases using A-type toxin. Because EMG is within biological electricity,its signal is weak and prone to interference. We designed a processing circuit,which used two separate amplification and filtering to extract the EMG. The characteristics of the signal processing circuit showed the proposed circuit could effectively extract the EMG form 10Hz to 500Hz, and restrain the frequency interference. Therefore the circuit would achieve in future practice. |
