The role of one-dimensional (I-D) digital FIR lossless matrices in the design of FIR perfect reconstruction QMF banks has been explored in several recent articles. Structures which can realize the complete family of FIR lossless transfer matrices have also been developed, with QMF application in mind. For the case of 2-D QMF banks, the same concept of lossless polyphase matrix has been used to ...
