## Homework Statement

This is a question from a Physics Lab i recently completed. We used a function generator to provide a signal to a spectrum analyzer that performed a Fourier transform on the signal. In this case the signal was a square wave. When viewing the Fourier transform on a log scale, smaller peaks were being produced of a constant magnitude compared to the main Fourier peaks that incrementally dropped in magnitude. What do these smaller peaks correspond to?

## Homework Equations

## The Attempt at a Solution

The only thing i can come up with is that the signal was not totally pure? I really don't understand Fourier transforms all that well.
