Comment on How a bad RJ45 termination can ruin a cableparent

It is a bit funny that your verdict is that someone is "ignorant" of the black magic in high speed communication, and you're linking to someone who literally has called two of his books "Black Magic".

Now I don't happen to agree with 'userbinator's skepticism -- indeed I think that a lot of engineers who work with digital stuff tend to forget that it is analog under the hood, with all the associated crosstalk and BER problems. But creating this atmosphere of "Ooooooh, it is something you probably don't understand" isn't very productive, if you know what I mean. I wish Johnson had titled his books, "High-Speed Digital Design: Quite Simple If You Do the Math and Physics".

I see the point that you and 'uberbinator' were making; "ignorant" was a poor choice of words on my part.

I intentionally used the words "black magic" because I was going to link to Johnson's books. While Johnson's publisher (not Johnson) probably named the books, I like the titles. The words you suggest may be more appropriate but the actual titles are definitely "catchier".
