Periodic Signal Definition
- For a Continuous-time signal
There exists a positive value of T for which
$ x(t) = x(t - T) $
for all values of t.
- For a Discrete-time signal
There exists a positive integer N for which
$ x[n] = x[n + N] $
for all values of n.
Note: N is the period of the signal.
Problems
- Periodic Continuous-Time Signal
- Not Periodic Continuous-Time Signal
