Abstract :
This article considers filter banks for subband coding of discrete time electrocardiogram (ECG) signals. A parallel FIR filter bank is optimized and compared with a classic tree-structured filter bank. Ringing noise is reduced by restricting the filter response lengths. Coding experiments show visual improvements of the reconstructed ECG waveforms, and a decrease in signal distortion from 0.6 to 0.8 56 PRD compared to the reference filter bank
