A method used to design filter banks that allow one to split the spectrum of a signal into non-uniform width subbands is presented. The filters of the banks are obtained by cosine modulation of more than one prototype. The prototypes are designed by imposing the cancellation of the main component of aliasing in the reconstructed signal. Aliasing components and their cancellation in rational sampling factors banks are described and design examples are presented.
