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
