摘要
心电信号是一种基本的人体信号,其中常带有肌电干扰、基线漂移和工频干扰等各种噪声,为了得到不失真的原始心电信号,在显示信号前要进行必要的滤波预处理。介绍了处理ECG信号中滤波器的设计,包括去除噪声的低通、高通和带阻滤波器。
ECG is a basic physiological signal, it contains EMG noise, the baseline drift and power-line interference, in order to get the tmdistorted original ECG, filtering is necessary before displaying. In this paper, the design of filters that used in ECG signal processing is discussed, including low-pass filter, high-pass filter and notch filter.
