| Abstract: | Based on the multi resolution decomposition capability of wavelet transform, an algorithm for ECG signal denoising is analyzed and designed in light of the different characteristics of signal and noise. Attention is concentrated on the dual scale pre process approach of the algorithm. The experiment shows that the algorithm not only can denoise on line and efficiently, but can also locate discontinuity points in the primary signal. |

| Keywords: | wavelet transform ECG signal denoising dual scale pre process module maximum |
