Electronic circuits - square wave vs. sine wave (audio differences)
Last updated on December 26, 2017, 11:29 by Sebastian Mihai
I've built this circuit to listen to the audio differences between square waves and sine waves. The sine wave sound is harmonically-pure and warm (even soothing).
The square wave sound is harsh, strident; it is somewhat reminiscent of older video game systems. The original Game Boy's two out of four audio channels generated square waves, giving its particular audio characteristics.
