The design process is reduced to designing the filter bank to satisfy a set of conditions and it
is known that the reconstructed signal always possesses some alias and distortion. It is the
present objective to find the necessary and sufficient conditions on the filters so that the
resulting QMF (quadrature mirror filter) bank cancels most alias components. Having found
these conditions, the author suggests an algorithm to design the PAC (partial alias
cancellation) QMF bank. Examples are given to demonstrate the theory.<>
