| Abstract: | Objection: baseline drift,frequency interference and EMG interference three main noises contained in the ECG signal were filtered,in order to obtain clean and effective clinical ECG information.Method: the improved threshold processing function of wavelet transform threshold denoising method.Conclusion: The improved threshold processing function wavelet threshold denoising method could make up of the shortcomings in the soft and hard threshold function de-noising method and get better denoising results. |
