摘要：
The authors consider the design of quadrature mirror filter (QMF) banks using digital allpass filters. The QMF banks consisting of an allpass filter and a pure delay section have an approximately linear phase response, and the phase distortion can be minimised by using another additional allpass filter as an equaliser.
