Fourier series animation using phasor addition 9

Posted by Steve Eddins,

I just saw a great animation illustrating the Fourier series decomposition of a square wave. Check it out. The video includes two different animations, so be sure to watch it all the way through to see the second one.

Hildo—It's not my code. I just posted a link to the animation. You'll have to contact the author.

This is very helpful. Thanks for posting. I shared this with my faculty colleagues and got several positive comments. As you can imagine, it's pretty tough to get much response to anything from faculty...unless it's a gripe session about the administration. ;-)

Dear Steve and All, Thanks for your interest for the animation. I have finally found out that this post is the reason for the increased interest for my video. Although very similar code has already been given by Amro and Lateef, I have included the original code to Matlab Central in the following link. Fourier Series Animation using Circles Thanks, Mehmet
