皮肤肌电信号分析，DB4小波包变换，时频分析-semg analysis db4 wavelet packet transform

表面肌电信号与肢体运动直接相关，肢体的不同动作具有不同的肌肉收缩模式，这些模式的差别反映在表面肌电信号特征的差异上-Surface EMG and limb movements directly related to the different movements of the limbs have different muscle contraction mode, the difference between these patterns reflect differences in sEM

是一篇关于表面肌电信号处理的文章，主要是模式识别方面的。-Is an article about the surface EMG signal processing, pattern recognition is the main area.

是一篇关于表面肌电信号处理的文章，主要是下肢sEMG模式识别方面的。-Is an article about the surface EMG signal processing, mainly lower limb sEMG pattern recognition.
