In this study, we are concerned with the effect of certain linear transformations of a signal f
on its phase. We are, in particular, interested in phase distortions caused by band-limiting
operations. The band-limiting operators serve as a motivation for studying the class of phase-
preserving operators. This class will be completely characterized.
