In this correspondence, we investigate on the problem of designing biorthogonal filter banks obtained by the cosine-modulation of an analysis and a synthesis prototype. The design procedure is developed in a general framework including both finite impulse response (FIR) and causal infinite impulse response (IIR) prototypes. Numerical examples are presented to show the effectiveness of the method.

Abstract
In this correspondence, we investigate on the problem of designing biorthogonal filter banks obtained by the cosine-modulation of an analysis and a synthesis prototype. The design procedure is developed in a general framework including both finite impulse response (FIR) and causal infinite impulse response (IIR) prototypes. Numerical examples are presented to show the effectiveness of the method.
