Periodic Function
I chose the function that Nicholas Browdues has used in the previous Homework 1 assignment as my reference signal. x(t)=sin(t) from 0 to 8*pi
This function is periodic as long as it is evaluated at values of 2*pi invtervals.
The way this function can be non periodic is if it is evaluated at integer values for a given t in a function.
t=0:1:25 x=sin(t) plot(t, x, '-o')
