摘要
工频干扰是各类基于PC应用系统中最常见的一种干扰信号,对有用信号的检测起着极大的妨碍作用。本文以自适应相干模板法为基础,讨论该方法在基于PC应用系统(如数字心电图系统)中去除工频干扰的快速实现问题。
The interference by 50-Hz noise arising from the power supply cables is common in PC-based application system, often considerably affecting the detection of useful signals. On the basis of self-adapting correlation method, we attempt to address the problem of fast elimination of 50-Hz noise from the useful signals in PC-based application system such as digital ECG recording system.
