| Abstract: | This paper discusses how to apply adaptive cancellation to cancel electrosurgical interference from ECG sig-nal.Based on the component of the electrosurgical interference,the filter system is used to remove the high frequent in-terference.The adaptive noise cancellation system is used to trace and remove the interference from the signal.The dy-namic simulation has been put forward by MATLAB language to evaluate its effectiveness. |
