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. Thing2 ECE301Fall2008mboutin.jpg


This is the same function but its values have been taken in Discrete time.

t=0:1:25
x=sin(t)
plot(t, x, '-o')

Thing3 ECE301Fall2008mboutin.jpg

This graph is non-periodic at this sampling due to the fact that the function cannot find good values to evaluate the system for integer values that are not multiples of pi.



Part 2

I also referenced Nicholas Browdues non periodic function from homework 1. His function was:

x(t) = e( − t / 20) * sin(2t)

t=0:0.1:8*pi
x = exp(-t / 20) .* sin(2*t)
plot(t,x,'--o')
