摘　　要：研究以Multisim 13中安捷伦函数发生器内置的心电信号(Electrocardiogram signal,ECG)和将MIT-BIH数据库中的ECG原始数据导入Multisim 13构成仿真信号源。在此基础上,完成滤除原始心电信号存在的基线漂移、肌电干扰和50 Hz工频等干扰信号的设计。通过仿真,表明了心电信号源和滤波器设计的准确和性能稳定。The study was based on an ECG embedded in Agilent function generator and the ECG data from the MIT-BIH, which is used to simulate the signal source of Multisim 13. On this basis, the design of filtering the interference signals such as base drift, myocardial disturbance and 50 Hz frequency of the original electrocardio signal was completed. The simulation results show that the design of ECG signal source and filter is accurate and stable.
