This java applet demonstrates Fourier series,which is a method of expressing an arbitrary periodic function asa sum of cosine terms. In other words, Fourier series can be used to express afunction in terms of the frequencies (harmonics) it is composed of.
To select a function, you may press one of the following buttons:Sine, Triangle, Sawtooth, Square, and Noise. The function isdisplayed in white, with the Fourier series approximation in red.You can edit the function directly by clicking on it.
This applet has sound if you are using java 2. If you don't see a "Sound"checkbox, then you should get theJava plug-in. The source.Version 1.6a, posted 9/29/05 java@falstad.com |
