Abstract

Removal of baseline wander and power line interference in ECG signal is a classical problem. A new method is proposed to remove baseline wander and power line interference in ECG signal based on empirical mode decomposition and notch filter. Principles and characteristics of empirical mode decomposition are presented; ECG signal is decomposed into a series of intrinsic mode functions (IMFs). Then 50Hz notch filter is designed, by which the IMF of ECG signal containing 50Hz power line inference is filtered. The "clean" ECG signal is reconstructed by properly selecting IMFs. To evaluate the performance of the filter, clinic ECG signals are used. Results indicate that the baseline wander and power line interference of ECG are removed effectively by this new method
