Theory of uniform DFT, parallel, quadrature mirror filter banks
Kumar Swaminathan, P. Vaidyanathan · 2005
A general framework is developed for uniform DFT, parallel quadrature mirror filter banks, which enables us to derive a number of conclusions in an elegant manner. Closed form expressions for the synthesis filters are obtained both for FIR and IIR case, and a number of properties of importance are placed in evidence.
