In engineering, signal processing, and mathematics, Fourier analysis decomposes general functions into a sum of sine waves of various frequencies.
Sine waves occur often in physics, including wind waves, sound waves, and light waves. In mechanics, as a linear motion over time, this is simple harmonic motion as rotation, it corresponds to uniform circular motion.
Both waves are sinusoids of the same frequency but different phases.Ī sine wave, sinusoidal wave, or sinusoid (symbol: ∿) is a periodic wave whose waveform (shape) is the trigonometric sine function. Tracing the x component results in a cosine wave (blue). Tracing the y component of a circle while going around the circle results in a sine wave (red).
