| Abstract: | ECG is a basic physiological signal,it contains EMG noise,the baseline drift and power-line interference,in order to get the undistorted original ECG,filtering is necessary before displaying.In this paper,the design of filters that used in ECG signal processing is discussed,including low-pass filter,high-pass filter and notch filter. |
