Rod, I appreciate your helpful spirit, but the WP articles that you're
citing aren't really anything like what I'm looking for.  The workings
of a/d hardware aren't an issue because the chip has built-in
converters.  I'm trying to figure out what to do AFTER the a/d
conversion.  I also know my way around Wikipedia pretty well and can
usually find clusters of articles in it myself without much trouble,
though it's often useful to get a pointer to a specific article on a
particular topic if that topic is relevant.  

In this particular case I was hoping to find a general overview of
modulation techniques for sending bits over analog channels, i.e. that
explains the different modem implementation schemes that have come up in
this thread, so (for example) I could better understand the types of
issues Andrew was mentioning regarding FSK decoding.

I've located some OCW lectures on data communication that are the sort
of thing I had in mind, though maybe I was hoping to concentrate at
first on simpler schemes suitable for microcontrollers.  Anyway, this is
a start:
