Research on ECG signal filtering algorithm based on the fusion of multiple algorithms

摘要

Digital filtering algorithm integrated by smoothing filtering and Kalman filtering is used to inhibit the narrow-band interference and fluctuation noise caused by power line interference, EMG interference and internal noise. Filtering algorithm proves to be very effective with the comparison of SNR gain, cross-correlation coefficient and mean square error. The advantage of time-domain filtering can ensure the processing speed of real-time application.
