Fourier
Synthesis Fourier Series
How to play:
- Left click and drag the [ball, green] circles to change the magnitude of each Fourier functions [Sin nf, Cos nf].
- Right click the mouse button to change the magnitude between 0 and 1.0
- Click Play to turn on the sound effect, Stop to turn it off.
- The coefficient of sin(0f) is used as amplification factor for all modes.
- (Use it to change the sound level)¡Athe coefficient of cos(0f) is the DC component.
- Click the checkbox at the top(after stop) will show square the the amplitude of the signal.
