摘要
心电信号是一种微弱的低频信号,极易受到噪声干扰,受到干扰的心电信号的波形会发生形变,影响医生对心电图的识别。采用基于凯撒窗函数的FIR滤波器、巴特沃斯滤波器、中值滤波器分别对心电信号中的工频干扰、肌电干扰、基线漂移进行滤波处理。
ECG is a weak low frequency signal, which is easily disturbed by noise. The waveform of the disturbed ECG signals will deform and affect the doctor＇s recognition of the electrocardiogram. Uses the FIR filter based on the Kaiser window function, Butterworth filter and median filter to filter the power frequency interference, EMG and baseline drift in ECG signals.
