Abstract

The Paley–Wiener criterion involving the issue of the physical realizability of any linear time-invariant (LTI) system / filter is well known in the literature. This criterion gives us the frequency domain condition on the magnitude of the transfer function of the LTI system. In this letter, we extend this criterion to linear canonical transform domains.
