All I can say is that I truly thank God for very intelligent folks like 
yourself & Frank Foti, and so many others here, who fully understand this stuff and 
make it almost look easy. :) Me, I just grasp the *concepts*. I think of this 
in terms of what I have seen on an oscilloscope & spectrum display. You've 
got the nitty gritty down to a science, literally. That's going well below the 
"surface", where I'm at! I'm a tinkerer, you're an order of magnitude beyond 
that.

Man, I love this... I really do! It leaves me scratching my head in 
amazement! Thank you! :)
