Filter Design for Orthogonal Two-Channel Filter Bank - Example

The Matlab commands below produce the filter illustrated in the figure. The Matlab programs can be down loaded from the previous page.

        L = 18;                 % length of filter h
        N = 5;                  % degree of flatness
        del = 0.03;             % size of ripple (in magnitude squared)
        [h,h2,h2] = fir_orthog(L,N,del);
