Leaner Fourier transforms: New algorithm can separate signals into their individual frequencies using a minimal number of samples

more »

A new algorithm performs Fourier transforms using a minimal number of samples. 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.
