WFILT_MBAND Generates 4-band coder Usage: [h,g,a] = wfilt_mband(N); [h,g,a]=WFILT_MBAND(1) returns linear-phase 4-band filters from the reference. The filters are not actually proper wavelet filters, because the scaling filter is not regular, therefore it is not stable under iterations (does not converge to a scaling function). Examples: --------- : wfiltinfo('mband1'); References: O. Alkin and H. Caglar. Design of efficient M-band coders with linear-phase and perfect-reconstruction properties.
