Two-channel perfect reconstruction FIR filter banks over commutative rings Academic Article

abstract

• The relation between ladder and lattice implementations of two-channel filter banks is discussed and it is shown that these two concepts differ in general. An elementary proof is given for the fact that over any integral domain which is not a field there exist causal realizable perfect reconstructing filter banks that cannot be implemented with causal lifting filters. A complete parametrization of filter banks with coefficients in local rings and semiperfect rings is given. 2000 Academic Press.
