摘要：

This correspondence derives necessary and sufficient conditions for a multirate linear phase FIR tilter bank, acting on a symmetrically extended finite-length input signal, to produce either symmetric or antisymmetric downsampled subbands. Such techniques have gained popularity recently for image coding applications, and we provide the solution to a key technical problem in terms of the input and filter symmetries and the downsampling ratio.
