Abstract :
The paper treats the problem of designing efficient FIR analysis-synthesis filter banks with system delays that can be pre-specified. A framework is introduced that is comprised of the cascade of several distinctive matrices with invertibility properties. The explicit form of the matrices guarantees computational efficiency and exact reconstruction, and allows for control over the system delay
