A signal is a periodic signal if it completes a pattern within a measurable time frame, called a period and repeats that pattern over identical subsequent periods. The completion of a full pattern is called a cycle. A period is defined as the amount of time (expressed in seconds) required to complete one full cycle. is far from satisfactoryWebRectangular periodicity, as considered here, allows an easy generalization. As in the 1-D case, we note that regular convolution is not possible with periodic sequences, since they have infinite energy. We offer next a proof of the periodic convolution property.
