CT scanning, streaming videos, and sending images on the internet will not be possible Fast Fourier TransformComputer algorithm is usually known as FFT, usually known by researchers Printon University and IBM According to an entry, every electronic device is found in the bus. Engineering and Technology History Wiki,
Performed for the first time in 1964 by IEEE Fellow John Tuki And James W. KoliThe algorithm breaks a signal – a series of values over time – and converts it into frequencies. FFT was 100 times faster than current Discomfort furrier conversionDFT also requires more memory than FFT as it protects intermediate results during processing.
FFT has become an important tool to manipulate and analyze signals in many fields including audio processing, telecommunications, digital broadcasting and image analysis. It helps in filtering, compressed, eliminating the noise and modernizing the signs otherwise.
Today’s state -of -the -art technologies also have applications in the 60 -year -old universal computer code. Ayequantum computing, Self-driving carsAnd 5g Communication system.
FFT was remembered with an IEEE milestone during a ceremony held in May at Princeton University in May.
2024 IEEE president Tom Kaflin said at the ceremony, “Cooley-TuKey algorithm accelerated the DFT calculation.” “East methods require significantly more calculations, FFTs get a revolutionary success. By taking advantage of algebraic properties and periodicity, FFT reduces the number of operations, which made it particularly and practically possible for everyday tasks, replacing low skilled analog methods.”
A new mathematical equipment
In 1963, US President John F, a professor of Mathematics and Statistics in Princeton. Participated in Kennedy’s meeting. Science advisory committee According to Ethw entry, to discuss ways to detect underground nuclear tests.
Richard Garvin, who attended that meeting, was a physicist and engineer IBM Who previously played an important role in designing the hydrogen bomb. He died in May. Read about his attractive life in this month’s memorium.
Tuki told Garvin that he was working on accelerating the calculation of an existing method – Fourier Transform – thinking that it could help find out. His algorithm Mathematically changed a signal in your original domain, such as time or location, a frequency domain,
Garvin recognized his ability and asked the IBM to select a mathematical analyst to cooperate with Tuki. The person was Cooley, a research staff member working on numerical analysis and calculation projects.
If the furrier transform can be made fast, Garvin said, Cesmometer can be applied in the ground According to Cole, atomic bomb tests in countries around the Soviet Union to detect nuclear explosions, according to the Soviet Union, will not allow the Soviet Union tests. oral history Wiki in engineering and technology history. A sesmometer measures the ground vibration, which is converted into electrical signals and recorded as semograms.
To design the sensor for underground nuclear tests, however, “you have to process all seismic signals, and a large part of processing can be done by the furrier transform,” Koili said in its oral history. But “Computing power at that time was not enough to process all the signals you need to do so.”
FFT can calculate the frequency of a seismic sensor and produce images, IEEE Life Fellow Herold S. stone Said in the milestone incident. He is an image processing researcher and fellow emeritus NEC Laboratories AmericaIn Princeton, and a former IBM researcher.
Tukey and Cooley led the team that wrote a computer code that demonstrated the power of FFT.
“The performance of the Koli-Tuki algorithm revealed that it was 100 times faster,” Stone said. “It was so fast that it could keep it with seismic data.”
According to the Ethw entry, sensors using the algorithm were installed, and they detected atomic explosions within a 15 -kilometer radius from where they were exploded.
“Taking advantage of algebraic properties and periodicity, FFT reduced the number of operations, which made it particularly and practically practically possible for everyday tasks, replacing low efficient analog methods.” -2024 IEEE President Tom Kaflin
Kole and Tuki published in 1965 “”A algorithm for complex furrier series machine calculations“Describing the FFT process. The seminal paper developed digital signal processing technologies.
For his work, Tuki was awarded America National medal of science In 1973. He also received 1982 IEEE Medal of Honor “Contribution to spectral analysis of random processes and fast furrier transform algorithm.”
Cooley, who received 2002 IEEE KILBY Signal Processing Medal To carry forward FFT, there was a prominent person in the field of digital signal processing. Through their participation with the IEEE Digital Signal Processing Committee (known as today IEEE Signal Processing Society), He helped establish vocabulary and suggest research directions.
Although not one of the inventors, Garvin is credited with identifying that there were broad applications in the algorithm, especially in scientific and engineering fields.
“In today’s Lingo, Garvin helped Koili and Tuki together in the FFT ‘viral’,” Stone said.
“Garvin and Tuki asked for better information to Vanol and stopped the wars,” said the nephew of Frank Anscom, Tuki. “Cooley-Tukyy FFT upgraded the reason rapidly by giving a practical, simple solution to wavy data. Thanks to FFT, began to cross a technical rubicon: analog-to-digital machines.”
A sense of cooperation between academics and industry
Like so many innovations, the FFT came out of a collaboration between industry and academics, and it should be recognized for it, IEEE fellow Andrea Goldsmith said at the ceremony. She explained that she regularly works with FFT in her research projects. At the time of the incident, she was Princeton’s Dean of Engineering and Applied Sciences. This month he started his new place as president Stony Brook Universityin New York.
He said, “Thinking with basic research in our university laboratories, talking to people in the industry, and understanding how the research problems we work can benefit the industry after tomorrow or five years or 20 years, is incredibly important,” she said. “Some people consider engineering to be boring and drought and some that only nerd, but a lot of innovations have such beauty and creativity that we have developed, and I think FFT is an ideal example of this.”
FFT connects more than 270 other IEEE milestones. They are more than a marker of achievement, senior member of IEEE Life Bala S. Prasanna’s director said IEEE Region 1,
“They are a will for the spirit of human simplicity, perseverance and cooperation,” said Prasanna. “These milestones were more than only successes; they became catalysts for innovation, once enabling the progress of impossible. Each one ensures that the story behind these innovations is preserved, not only as history but as inspiration for future generations.”
Another Celebration Was held on 11 June IBM Watson Research Center.
Milestone straps that identify FFT are displayed in Princeton’s lobby Engineering and Applied Science School And in the main lobby at the entrance of the IBM Research Center.
they read:
“In 1964, a computer program applied to a highly efficient furrier analysis algorithm was displayed in IBM Research. Jointly developed by Princeton University and IBM colleagues, Koili-Tuki technology calculated the discontent furrier, which was shown rapidly than already displayed. Streaming.”
