**Fourier analysis**

What is Fourier analysis?

Fourier analysis is a mathematical technique that decomposes a function (often a signal) into its constituent frequencies. It is widely used in signal processing, image analysis, data compression, and solving differential equations. Essentially, it transforms a signal from its original domain (e.g., time or space) into a frequency domain representation, revealing the amplitudes of the various frequency components present in the original signal.
