A method for equalizer design based on symmetry of system's response to a band-limited signal is presented. The equalizer minimizes time-domain distortion, assuming that significant signal components are contained within the specified low-pass band o

Quadrature mirror filter (QMF) banks have been studied extensively because of their attractive properties, which are useful in many applications. One desirable property is perfect reconstruction, i.e. in the absence of any channel modifications the f
