This white-noise sounding signal with a flat spectrum is the pseudo-random bit sequence used to pre-train the adaptive equalizer that cleans up the mushy analog signal into clean bits.
It's basically a linear classifier trained with least square, a direct descendent of Bernie Widrow's Adaline (competitor of the Perceptron).
As a summer project I wanted to get some experience with LLMs and see how they might help provide some content for lesson activities for CS subjects. It was a fun project and I think it will be useful for other courses.
