Abstract :
A criterion which sufficiently guarantees the absence of overflow oscillations in two-dimensional digital filters in the state space is given. This criterion is used to identify a certain class of two-dimensional filters for which overflow oscillations are proved to be absent. Such filters, however, are noncanonic.
