Discrete Time Periodic Signals

Discrete Time Periodic Signals

Discrete Time Periodic Signals. Definition:. A discrete time signal x[ n ] is periodic with period N if and only if. for all n. Meaning : a periodic signal keeps repeating itself forever!. Example: a Sinusoid. Consider the Sinusoid:. It is periodic with period since.
