A Self-Reconfigurable Platform for the Implementation of 2D Filterbanks with Real and Complex-Valued Inputs, Outputs, and Filter Coefficients

Figure 6

2D Separable real-coefficients equiripple filterbank. The filterbank is composed of four 2D separable real-coefficient Filters. Note that filter #3 appears darker because its band-energy is distributed over four quadrants, as opposed to the spread over two quadrants for fitlers #2 and #4. We have also kept the maximum gain for the lowpass filter (#1) to be at the same levels as #2 and #4.
