How a 60-Year-Old Algorithm Powers Modern Technology

Speedy Summary:

• The Fast Fourier Transform (FFT) algorithm, developed in 1964 by John Tukey and James cooley from Princeton university and IBM, revolutionized Fourier analysis by being 100 times faster then its predecessor, the discrete Fourier transform (DFT).
• FFT’s ability to convert signals into frequencies enabled advancements in audio processing, telecommunications, digital broadcasting, image analysis, AI, quantum computing, self-driving cars, and 5G systems.
• The milestone invention addressed challenges such as nuclear test detection through seismic data processing at a time when computational power was limited.
• In subsequent years:

– Tukey received prestigious honors for his contributions to spectral analysis and FFT advancement.
– Cooley was recognized for his pioneering work in signal processing technologies.

• The IEEE Milestone plaques commemorating FFT are displayed at Princeton University’s School of Engineering and IBM Watson Research Center.
• At the recognition event at Princeton this year (May), IEEE leaders highlighted the collaborative spirit between academia and industry as key to innovation.
