Abstract :
A generalized continued-fraction (CF) expansion technique for two-dimensional (2-D) recursive digital filters is introduced. The conditions for realization and implementation of such an expansion are discussed. It is shown that all the structures so far known can be derived from such an expansion. Illustrative examples are also provided.
