Distortion anaysis of digital filters for ECG signals

ECG 신호를 위한 디지탈 필터의 distortion 해석

Distortion analysis of digital filters for the ECG signal processing is presented. Several band pass and band reject filters are designed for the analysis. Computer simulations are performed to compare the distortions of the Butterworth type filters and linear phase optimal fitters. The designed filters are applied to power line interference cancelling in ECG signals.
