Abstract :
Filters on the space of multidimensional semiperiodic signals are studied. We show that the filters on these signals whose transfer function is reasonably smooth satisfy many additional properties. As an application, we prove that semiperiodic solutions of a class of difference equations can be found under a condition weaker than those previously known
