Phasor

Wave
Spectrum

    

A phasor is a wave that rises from 0 to 1, and repeats at a steady frequency. It’s like a sawtooth wave, except always positive.

It’s useful for shaping sounds, as shown in the polynomial example.

What happens to the wave if you square the output of the phasor? (Don’t forget to lower the volume by multiplying the wave down at the end.)
