本文讨论了信号平均法去除噪声的基本原理,针对带有随机噪声的 ECG信号,利用 UW Digiscope程序进行了实验仿真,结果表明,该方法可以在不失真的前提下通过多次叠加提高信噪比,从而分离出目标信号,抑制了噪声.

Discusses the theory of canceling the noise in ECG by Average Evoked Response. Simulateds experimentally Average Evoked Response used for ECG with random noise by UW digiscope procedures. The experimental result shows that this method can extract objective signal, re...
