Abstract
In this paper, I consider about the theory of modulated 2 Dimensional (2-D) perfect reconstruction (PR) filters banks with permissible passbands. At first, I design a 2-D complex digital filter with half passband obtained by the sampling matrix. Next, 2-D analysis filter banks are realized by modulating this prototype 2-D complex digital filter and by taking the real part of the output. It is also shown that the modulation in 2-D frequency plane is equivalent to 1-D DFT. A necessary and sufficient condition for 2-D perfect reconstruction filter banks is derived. Finally I show some examples.
