中文说明:
表面肌电信号是肌肉收缩时伴随的电信号,是在体表无创检测肌肉活动的重要方法。由于设备采集到的肌电信号会受到环境噪声等影响,因此在进一步分析之前需要对采集的肌电信号进行去噪处理。 设计一种传统滤波器(如Buttterworth)和现代滤波器(Kalman)对所采集的肌电信号进行处理,并比较各个肌肉的做功比。
English Description:
Surface electromyography (sEMG) is an important noninvasive method to detect muscle activity on the body surface. Because the EMG signal collected by the device will be affected by the environmental noise, it is necessary to de noise the collected EMG signal before further analysis.
