Homework 2 Part A-1
I chose the signal:
$ y = cos(n)\, $
When I took a sample at 1 hz, the signal was ugly and random.
Therefore it is not periodic.

Changing the function to:$ y = cos(n*pi/2)\, $
made the signal look periodic.
Part A-2
I chose the signal y=log(x)
This code is not periodic, but taking a piece of it and
Repeating it will make it periodic
