Hve fun. Simulation requires Java.

Vibrating String (http://www.falstad.com/loadedstring/)

And lot's more acoustic simulations

You can do better ? Let's see some of your simulations. On second thought... http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

Also, you gotta enable the Java plug in, otherwise you get that strange symbol and that box that says "missing plug in" and I'll agree, thats pretty darned boring. http://www.qrz.com/iB_html/non-cgi/emoticons/biggrin.gif

And, if you are interested in mechanical things as well as electrons;

For the filter aficionados, it's the same Professor Tchebicheff/Chebyshev that we know.

Strange, both links work fine from here.

Thanks for the great link John. I am especially appreciative of the applet because with the sound enabled, I can hear the different tonal qualities from plucking a string further and further away from the middle.

Thanks here too John. Works well and it gives me a graphical idea of what's happening when I play my bass.

I didn't know that! I have a couple of pantographs that use the straight line generator, but had no idea who inventolated that!
