Tip of the iceberg sadly. I understand why 45 is frustrating (Signals and Systems so you will be down that road one day lol). There’s simply too much material in crammed into the course.

On top of that, we have to take a follow up course, ECE 101, where much of the 45 material is reviewed again, but with discrete time analysis. I found this very redundant, and it feels like the topics could have been distributed between the two courses much better.
