Periodic versus non-periodic functions (hw1, ECE301)
Read the instructor's comments here.
Periodic Function
A periodic function is a function that has repeating values after a certain period of time and keeps repeating as time continues.
CT periodic function:
$ y = sin(x) $
Non-Periodic Function
DT non-periodic function:
$ y = sin(x) $
Even though the equation is the same, this equation is in discrete time, so it's a non-periodic function.
