| 摘 要： | 表面肌电信号因其无创性被广泛应用,但因其为一组肌群的募集信息,所以包含了更多的噪声.本文针对这个问题通过仔细选择肌电信号的采集位置,在采用高精度的肌电采集系统及11 025 Hz的过采样率的基础上采集到多组表面肌电信号,结合肌电信号的特点利用小波变换中的消噪技术对不同频段的信号进行不同阈值的消噪处理.实验表明,该方法有很好的消噪效果.

| Abstract: | sEMG are widely adopted because of it's scot-free. While it includes more noise because the information be tested is a team of colleted information of group muscles . By choosing the collecting positions of the signals carefully and based on adopting high accuracy collecting system on 11025Hz high sample rate, we can collecting more teams of sEMG. Combining with the characters of the sEMG, this article aims at de-noising signals of different frequency band at different threshold by the de-noising technology... |
