Aydin et al. (1991) studied Electrocardiogram signals. Sub-band coding using quadrature mirror filter bank and various coding methods was evaluated on Compression ratio and visual distortion. A sub-band coding technique for ECG data compression achieved compression ratios as high as 5.7 without introducing any visual distortion.
