| Abstract: | The principles of zero phase digital filtering were discussed. By using the method introduced in this paper, the 50Hz power line interference with practically measured ECG signal was reduced. Some examples are presented, which can demonstrate the superiority of the method introduced in this paper. For ECG signal, the filtering capability of this method is more excellent than that of the ordinary Digital Filtering methods, especially for the QRS complexes of ECG signal. The method is very valuable for applications in ECG signal processing, analysis and automatic recognition. |
