中文说明：采集肌肉表面肌电信号一维离散数字信号，对采集到的表面肌电信号进行滤波处理，处理后进行表面肌电信号的标准化，对标准化后的信号需要提取时域特征参数，时域参数特征提取时，首先对信号进行加窗，对每个窗进行积分肌电值的求取，所得时间-积分肌电值信号，可以更好的提现信号特征。
English Description：
The one-dimensional discrete digital signal of muscle surface EMG signal is collected, and the collected surface EMG signal is filtered. After the processing, the surface EMG signal is standardized. The time-domain characteristic parameters of the standardized signal need to be extracted. When extracting the time-domain characteristic parameters, the signal is first windowed, and the integral EMG value of each window is calculated to obtain the time integral EMG value Signal, can better extract signal characteristics.
