QMF bank has three type of distortion: amplitude distortion, phase distortion and aliasing distortion.
If [G.sub.0](z) is not allpass, the filter bank suffers from amplitude distortion. If [G.sub.0](z) does not have linear phase, the filter bank suffers from phase distortion.
One use of an equalization system is to compensate for transmission-channel impairments such as frequency-dependent phase and amplitude distortion. Besides correcting for channel frequency-response anomalies, an equalizer can be used to cancel the effects of multipath signal components.
