De-noising of sEMG signals Based on Wavelet Transform
Hongli Yu · Journal of Hebei University of Technology · 2008
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 of wavelet transform. It turns out to be a good de-noising method.
