ECG心电信号预处理，高通滤波器，滤除呼吸基线漂移，带阻滤波器，滤除工频干扰，并两组滤波器的处理速度进行比较-ECG signal preprocessing, high-pass filter, filter respiratory baseline drift, band stop filter, filter frequency interference, and two filters to compare the proces

心电信号的预处理，包括多种滤波方式，经过测试，滤波效果很好-ECG signal preprocessing, including a variety of filtering methods, after testing, the filter effect is very good
