【Abstract】 Based on the characteristics between singular signal and noise, this paper studied wavelet denoise method for ECT signals. After analyzing the support signal, authors found its regularity, and introduced the new method of removing the support disturbance using wavelet multi\|scale edge detecting technology. The result shows that the method is better than the current one in the respect of hardware cost.更多还原
