Abstract:

A design method for wave digital lattice filters is presented which yields filters with maximally flat magnitude behaviour in the passband, equiripple in the stopband, and nearly constant group delay over the entire frequency range. The method starts with the specification of ideal allpass phases which produce the desired behaviour and then these specifications are approximated with actual allpasses. Equations for obtaining the allpasses and an algorithm for distributing the transmission zeros to give equiripple magnitude behaviour in the stopband are included as well as examples obtained with the design method.
