自适应噪声抵消在抑制高频电刀对心电监护仪干扰中的应用研究

The implication of the adaptive noise cancellation to suppress the electrosurgical interference from the ECG monitor

本文讨论了如何利用自适应噪声抵消去除高频电刀工作时对心电监护波形的干扰。本课题基于高频电刀干扰成分的研究 ,采用了滤波系统去除高频成分的干扰 ;利用了自适应噪声抵消系统实现对噪声的跟踪、去除。并利用MATLAB语言对抑制措施进行动态仿真 ,验证了抑制措施的可行性。

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.
