I'm starting a new thread (from "Sampling: What Nyquist Didn't Say, and What to Do About It"), because the old one rapidly filled up with all sorts of interesting stuff that I didn't want to detract from.
I've posted a new version. It uses Bitstream fonts for Roman -- used because it was mentioned, and because it was there. It's still a serif font which isn't optimum for monitor viewing, but I want the thing to look good when it's printed (and I'm lazy about figuring out how to tell Lyx/LaTeX how to use sans!).
It's 12-point, so you won't have to squint to see it, or have as much trouble scanning across the line. It certainly looks better in Evince, and I'm about to find out how it looks in Adobe, on my wife's computer upstairs.
And Randy, I've changed the discussion of subsampling to make it more clear -- I hope that if it doesn't fully answer your difficulties (I think you thought I was claiming to sample at an effectively infinite rate) it does explain what I'm thinking more fully.
THANK YOU ALL who responded to the previous thread, and please don't feel shy if you see something that I still haven't caught! I need to add an acknowledgements section for all the kind folks on USENET who critique my work.
