WebJan 9, 2024 · Periodic Signals edit source. 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. WebMay 22, 2024 · These discrete time complex exponentials have the following property, which will become evident through discussion of Euler's formula. e j ω n = e j ( ω + 2 π) n. Given this property, if we have a complex exponential with frequency ω + 2 π, then this signal "aliases" to a complex exponential with frequency ω, implying that the equation ...
