Abstract
In order to solve the problem that there are all kinds of interferences during the process of collecting ECG signal,according to the characteristics of multi scale and multi analysis based on the wavelet transform,the decomposing and rebuilding method was used for four scale-ECG signal filtering.The results showed that the method could filter 50 Hz interference,EMG interference and baseline drift.And it makes a good foundation for testing the QRS wave of ECG signal.
