The power frequency in 50Hz and its harmonic interference is one of the main noise sources during the acquisition process of surface electromyogram signals (SEMG), how to restrain interference power frequency and its harmonics effectively is one of the important issues on the EMG preprocessing. In this paper, we will determine the power frequency interference and its frequency of the harmonic through the signal acquisition, make the cross-correlation by the constructor and the collected data, and determine its magnitude. We can draw a conclusion that this method can effectively restrain power frequency interference of EMG during the acquisition process through the comparison of the power spectrum of de-noising before and after. The Experiments show that this method can effectively separate the power frequency interference during the acquisition process, and is suitable for the real-time processing of EMG.
