Indeed. The hardest thing to convince some digital designers is that
digital circuits AREN'T.

Especially when they are trying to examine signals with fast edges on a
100 MHz scope, and think the edges look just fine. A 100 MHz scope is
*usually* adequate for working with 74LS and 74HC logic, but with modern
CMOS it usually isn't.

We *try* to make digital circuits behave digitally, but a whole host of
things conspire against us.
