Webb23 nov. 2024 · Periodicity is a basic concept when it comes to signals, it means if the signal contains a pattern, which repeats itself after a specific period of time, we call it a periodic signal. The time it takes for a periodic signal to repeat itself is called the period 𝑃 , and the inverse of the period is named as frequency, 𝑓, for a signal with a period of 1 sec, …
