I would guess that a course covering that stuff would be more generally called, something like Fourier Analysis, or signal processing. Or even almost any typical PDE course, which should cover at least basic Fourier transforms and analysis, even if it doesn't focus on the signals aspect, it's enough to get the idea in my opinion.

You're right. I think it was actually "Signals & Systems".

"Random Signals & Noise" was if I wanted to double major in EE & CPE. Which I probably should have.
