In order to improve my DSP foundations and hone my programming skills
I've decided to write some programs to visually demonstrate various
concepts.
I'll start with something simple - linear superposition. It would be
accessible to someone with no background and I can work out just how I
want my user interface to work.
I would then have segments demonstrating
bin width vs window width and sampling frequency
types of windowing
aliasing
The problem I have with books is they have room for a limited number of
figures. Also, I'm a hands on type of learner I need to do "what if..."
Further selection of what to demonstrate will be whatever I have
problems with as I go back thru Rick Lyons' and Steve Smith's books.
Any suggestions of specific items I should include?
Is there a list of similar projects people have attempted?

They work much the same way excercises in textbooks do: By inspiring / forcing the programmer or student to think. I'd suggest you start with whatever you think is a good or interesting starting point and go on from there. Make some simple demos, then play with them, and always contemplate what you are up to.

Mr. Wizard did the experiment and left viewer thinking about "what if..."

I'm saying that you should do this on your own terms, following your own ideas and interests. But think as you go along. Rune

Showing superposition with a Java applet with slider bars, for instance, would be a neato thing on a "DSP basics" web page. -- www.wescottdesign.com

Yes, you are right. There might be some use in seeing these things. But to *really* learn from them, you have to make them. Rune

It is also why I'll do it in either Scilab or Tcl/Tk because I have a need to be proficient in those systems.
