Before understanding how noise behaves, we have to intuitively
understand what a power spectrum is. We will try to achieve that by
visually looking at the effect of changing some parameters on random signals.
Imagine that the signal
we are using for our experiment is a pitch signal.
This means that the values of the signal are pitches chosen (randomly or
deterministicly) in time for a single melody for a specified time.
