Jim, I really agree with you (sorry for the missing smileys). On one hand it is embarrassing when an old hand describes a proven circuit, and the younger crowd finds that it "doesn't work". On the other hand, I think that, especially with such a simple and peripheral circuit, it would be nice if engineers retained some basic understanding of physics and circuitry.
I have a running battle with people who think the X at the latch output (or flip-flop Q when the set-up time is violated) is an undefined, in-between mysterious level, instead of just an unknown (but physically real) state. Or with people who try to analyze metastability with logic simulation tools.
Designers should realize that real digital signals are High or Low (and rarely in-between), while 0 and 1 and X are just convenient abstractions that work most of the time, but not always. But I try my best not to become a cranky old fart. Hell, I am still proud of that cheap de-bouncing trick! Peter
