title: [Fast elimination of 50-Hz noise in PC-based application system].
abstract: 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.
