| Abstract: | The measured ECG signals inevitably have some strong interference and noise. In order to accurately extract the characteristics of the ECG signal, a noise reduction method that based on one-dimensional discrete wavelet transform is discussed in this paper. The results demonstrate that this method can effectively reduce the noise of the ECG signals,thus establishes the theoretical foundation for extracting features information of ECG signals. |
