You mean they don't always have to be "voltages". Agreed. I only wanted to emphasize that at the physical level, they are not discrete. In this case, they happen to be represented as voltage drops.

Agreed.

I wish more people would take the time to look at the classic CMOS inverter: Looking at the VIn vs. VOut graph, it is overwhelmingly obvious that the word "digital" refers only to a higher level of abstraction for circuits that, in reality, are analog. (And more to the point, these SAME circuits are used as amplifiers in a typical analog design.)

Good luck explaining this to a CS major.

That's funny. I am really a CS guy. Just happened to work for a semiconductor company for a few years after college.
