| Abstract: | In order to inhibit noise interference for extracting the characteristics of ECG signals,a noise reduction method based on one-dimensional discrete wavelet transform was discussed in this paper. The results obtained by simulation of the MIT/BIH ECG database demonstrate this method can effectively reduce the noise of ECG signals,which provide a certain practical value for extracting features information of ECG signals. |
