6-9 credit course of courses and you’re a circuit designer? You are dreaming. Which capacitors are used for what function? What kind of trouble can you get into if your comparator is too fast? Do they tell you that a 7800 series regulator needs a load? Going to school is good. But if the alternative is 6-9 course hours, I’ll get further with scope, meter, soldering iron, app notes, and LTSpice in the same time than that student. And I assure you, from the bottom of my heart, as a near-expert in both, that the Fourier analysis in quantum mechanics, solid state physics, optics, etc. bears little resemblance to that used in signals and systems and DSP. LITTLE. RESEMBLANCE.

> New graduates in EE also can't do the things you listed :)

That was the spirit of my point, yes :)

More than once I've heard a coworker complain that "I wish I had learned about that in school instead of [filler course so useless that I forgot what they said]."

Very good point. Often I think the hardest part about being an EE is using our CAD tools.

Gaussian units seem to be on their way out. I, for one, won't miss them. (Or cgs.)

The Z-transform is much more related to the others than is clear at first glance. This post on transforms [0] from the The n-Category Café is fascinating, and my go-to for understanding what the Laplace transform really is, even if I don't quite grasp many things in the post. (And I also have a math degree! But not a graduate one in active use, as most of the people around there do.)
