From: brent on 7 Sep 2009 07:56 Hi, I have created a Fourier Transform tutorial. It is located here: http://www.fourier-series.com/f-transform/index.html It uses interactive flash programs to help you see how the fourier transform works. There are currently 5 flash modules with lots of embedded audio in each module. The site also includes tutorials on the fourier series, complex numbers, the discrete fourier transform and some radio frequency topics.

Thanks :-)

As far as i can tell so far you have a good handle on the material. You do need to polish up the audio tracks, there are far too many pauses, umms, ahhs and the like. There is still too little follow through on how the math works out. Try linking to much more detailed math, not much need to put it in the mainline. If you can find a copy try E. Oran Brigham's "The Fourier Transform", It may really help you with the presentation.

This website is intended for someone who already has looked over the math equations and cannot visualize what they mean. The hope is after they go through this site, they will be able to go back to their text book and be able to make progress. The motivation came from me being a student and not really getting any of this stuff until I pondered it a long time and saw a few "ah-ha"s. I am trying to get them to see the ah-ha 's quickly. As far as the audio goes -- I know it is amateurish. It is just incredibly difficult to do the audio right. I have a real new found respect for good narration. My intent is for the user to play with the program, and the narration is there as kind of an instruction manual. Brent

Good to see that you are still alive. Brent PS Oops - maybe that was not such a great way of putting it . |
