【摘要】 心电信号是一种基本的人体生理信号,然而体表检测人体心电信号中常带有工频干扰、基线漂移和肌电干扰等各种噪声,为了消除心电信号检测过程中带有的上述3种噪声,采用MATLAB有针对性的设计了三种数字滤波器来滤除相应干扰。更多还原

【Abstract】 ECG is a basic physiological signal. However, ECG detection of human body surface is with frequency interference, the baseline drift and EMG noise.To eliminate the three noise, the three digital filter is designed on MATLAB to filter out the corresponding interference.更多还原
