I have enjoyed these discussions also! Thanks for the links. 

If any of you are going to Dayton Hamvention this year, Phil will be
presenting on DSP and is along these same lines with simple tool. He was a
presenter in the SDR forum 2 years ago and his presentation makes
understanding his subject very simple, for beginners as well as experts.

Abstract:

A simple Approach to Learning Digital Signal Processing - Phil Harman -
VK6APH 
One of the problems a beginner faces in learning Digital Signal Processing
(DSP) is finding a simple tool to aid the learning process. Whilst such
tools do exist they are generally aimed at the professional and come at a
professional price. There is an urgent need to provide beginners with a
"crystal set" approach to learning DSP and with a similar price tag. Phil
Harman, VK6APH, will describe a technique for learning DSP that uses freely
available software that enables the beginner to build an extensive array of
digital test equipment - from a simple signal generator right up to a high
performance spectrum analyzer. The test equipment enables the beginner to
experiment with digital filters, modulation and demodulation techniques - as
they say, "to learn by doing". 


Thanks

I re-found a reference that is really handy... one I started searching
for when this thread first began.  It's a book from Analog Devices which
is available on line for free.  In the mid to late 90's they were giving
these away at one-day seminars on DSP.  It's an easy to understand
description of the basics or signal processing.  

Here is a link to the chapter on sampling (it is relevant to this
thread).

...and here is a link to the whole of the book.
