EECS20N: Signals and Systems


The quality of a musical sound that distinguishes one musical instrument from another is called timbre. Timbre is due in part to the fact that musical instruments do not produce purely sinusoidal sounds. Instead, to a first approximation, they produce sounds that consist of a fundamental sinusoidal component and harmonics. The fundamental is at the frequency of the note being played, and the harmonics are at multiples of that frequency. In the following applet, you can adjust the relative weighting of the fundamental and harmonics for a musical sound.
If you were able to run applets, you would have an applet here.
