摘要
文中讨论了去除心电信号工频干扰的几种数字滤波器设计方法,从实用性角度对其滤波性能和实现方法进行比较。实验表明,简单整系数滤波器和自适应滤波器对于心电信号中工频干扰的滤除具有较好的综合性能。
Several digital filtering technique for eliminating power - line interference from ECG signals are presented in this paper. Their filtering abilites and realization methods are compared from practical view. Experimental result shows that simple integral coefficient recursive digital filter and adaptive filter have the best comprehensive performance.
