An audio waveform theoretically comprised of an infinite set of harmonically related sine waves, as shown under Law of Superposition. It is often used in sound synthesis. See also: Fourier Theorem, ...

Also, triangular wave. An audio waveform theoretically comprised of an infinite set of odd harmonic sine waves. It is often used in sound synthesis where its timbre is less harsh than the square wave ...

This is a sine wave, they say, this is a sawtooth, this is a square wave, and so on. We’re taught to look at the lines on the screen as idealised, a square wave is truly square, and the ...
