The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing. The algorithm allowed computers to quickly perform Fourier transforms—fundamental operations that separate signals into their individual frequencies—leading to developments in audio and video engineering and digital data compression.
