sine wave

Smooth periodic mathematical curve

A sine wave is a smooth, repetitive oscillation that graphs as a continuous S-shaped curve—the mathematical representation of pure periodic motion.

It describes how things vibrate or cycle in physics: sound waves, alternating current, pendulum swings.

The shape comes from plotting the sine function over time.

The synthesizer produces a clean sine wave.
