Adaptive noise cancellation for SQUID-based magnetocardiogram
射频SQUID心磁图数据自适应滤波研究

This paper presents the implementation about adaptive noise cancellation by prov iding several kinds of algorithms with the objective of removing the 50Hz noi se from magnetocardiogram(MCG) based on SQUID. The computer simulation results o f the algorithms are given for comparison. The result shows that 50Hz power li ne noise in MCG taken by SQUID has been fairly well eliminated by an adaptive no ise canceller.
