Design of Approximately Linear-phase Allpass-based Qmf Banks

Allpass-Based QMF Banks Chung-Kuei Lu, Martin Anderson and Steve Summer eld University of Warwick Coventry CV4 7AL UK (+44) 1203 523780 marcx@eng.warwick.ac.uk Abstract In this paper, the authors present a direct method to design allpass-based QMF banks with approximately linear phase. In order to achieve this, the phase responses of the allpass branches split by =2 either side of the average linear phase of the lter. Several design examples are given to illustrate the proposed method.
