%X Finite\|length input signal will introduce extension or distortion in wavelet transform. Analyzing the impact of symmetric extension on analysis/synthesis system, this paper presents optimal symmetric extension of finite\|length input signal and delay of filters in subband coding which produces perfect reconstruction and overall zero\|delay.
