| 摘 要： | 本文根据心电实时监护的要求,应用整系数线性相位数字滤波器对心电信号作预处理,包括50Hz 工频干扰的陷波(带阻滤波)及高频噪声抑制(低通滤波)。文章叙述了整系数数字滤波器的设计过程,在实际滤波效果与计算量的减省方面均取得了较好的效果。

| Abstract: | According to the requirements of ECG real-time monitoring,inte-ger coefficient linear phase digital filters,including 50 Hz notchfilter and high frequency noise suppression (low pass filter),wereused for pre-processing of ECG signals.This paper describes thedesign process of digital integer coefficient filters.The results offiltering indicated that these filters were good in both performanceof processing and reduction in amount of computing. |
