Joseph Fourier

Joseph Fourier was a mathematician and physicist known for discovering that complex signals, such as sound or temperature variations, can be broken down into simple waves called sine and cosine functions. This method, called Fourier analysis, allows us to analyze and understand signals more easily by examining their basic components. Fourier's work is fundamental in fields like engineering, acoustics, and signal processing, enabling the transformation of complex data into simpler parts for analysis, transmission, and filtering. His insights help us better understand many natural and technological phenomena involving wave-like behavior.
