3.2 Periodic and Non-Periodic - Computer Networking concepts


Periodic Signal

Periodic Signals are signals that repeat themselves after a certain amount of time. More formally, a function f(t) is periodic if f(t + T) = f(t) for some T and all t. The classic example of a periodic function is sin(x) since sin(x + 2 π) = sin(x). However, we do not restrict attention to sinusoidal functions.
