Continuous Time
Periodic signals
A periodic signal is one that for a given real number "a": $ x(t) = x(t+a) $

Non Periodic signals
Non-periodic signals are those which no value of "a" satisfies the following equation. $ x(t) = x(t+a) $

Discrete Time
Periodic Signal
A periodic discrete time signal is one that satisfies :
$ x[n] = x[n + A] $
For a given integer value 'A'
