Abstract :
In de Queiroz and Rao (1995), new expressions were developed for the perfect reconstruction (PR) of the boundary regions of a finite-length signal after subband processing using uniform and paraunitary filter banks (PUFBs). The present paper points out an incorrect assertion in the previous paper regarding the sufficiency of its solution and presents the general existence (applicability) conditions for the method. Furthermore, we extend the method to encompass perfect reconstruction filter banks, i.e., not only the paraunitary case
