| Abstract: | A new adaptive filter based on wavelet transform is described. The reference signal of the adaptive filter is derived from the high frequency bands of original ECG signals decomposed by wavelet transform. To evaluate the performance of the filter, MIT/BIH database is used, which proved that the filter can remove baseline drift effectively. |
