Abstract
A structure for implementing lapped transforms with time-varying block sizes is discussed. It allows full orthogonality in the transitions based on a factorization of the transfer matrix into orthogonal factors. Such an approach can be viewed as a sequence of stages with variable-block-size transforms intermediated by sample-shuffling (delay) stages. Details for a first order system are given and a design example is presented
