unusual facts about square wave



Electric current

In certain applications, different waveforms are used, such as triangular or square waves.

Hudson Soft HuC6280

White noise is used to simulate percussion instruments and effects, such as explosions, by means of a pseudo-random square wave.

Pulse-frequency modulation

It is analogous to Pulse-Width Modulation (PWM), in which the magnitude of an analog signal is encoded in the duty cycle of a square wave.

Yamaha AN1x

Available waveforms include PWM-capable saw and square, saw2 (behaves in a different way than "saw" when used with PWM), a saw/square "mix", additional waves (Inner1-3) for OSC1 in oscillator sync mode, triangle and sine by altering the Edge of pulse waves (or any wave for the sine), and various intermediate waves available through Edge.
