对肌电信号中的有用信号的提取，将无用信号幅度变为-EMG to extract the useful signal, the signal amplitude becomes useless

将信号（本程序原本用于处理肌电信号）进行放大、滤波等处理后，在用本程序求取该段信号的平均功率频率（内附可用于测试的肌电信号数据）。-The signal (the Program for processing original EMG) amplification, filtering and other processing, using the procedures for obtaining the average power of the frequency of the signal

对肌电信号进行简单的时频分析，包括RMS，肌电积分值，动态中值频率，近似熵，边际谱熵等-HHT Marginal Spectrum Entropy
