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. … See more We will discuss here some of the common terminology that pertains to a periodic function. Let g(t) be a periodic function satisfying g(t + T) = g(t) for all t. See more There are some common periodic signals that are given names of their own. We will list those signals here, and discuss them. See more Periodic functions can be classified in a number of ways. one of the ways that they can be classified is according to their symmetry.
