For a large range of practically useful cases, MIT researchers find a way to increase the speed of one of the most important algorithms in the information sciences. The Fourier transform is one of the ...

The Fourier transform is one of the most fundamental concepts in the information sciences. It’s a method for representing an irregular signal — such as the voltage fluctuations in the wire that ...

A group of MIT researchers believe they’ve found a way to speed up audio, video, and image compression by improving on the Fourier Transform. They say the new algorithm is up to ten times faster than ...

This repository contains a C++ implementation of the Fast Fourier Transform (FFT) algorithm. The FFT is an efficient algorithm to compute the Discrete Fourier Transform (DFT) and its inverse. This ...

The Fast Fourier Transform (FFT) remains a cornerstone of digital signal processing, underpinning applications from telecommunications to medical imaging. Modern FFT processors and architectures have ...

The Fourier transform is one of the most fundamental concepts in the information sciences. It's a method for representing an irregular signal — such as the voltage fluctuations in the wire that ...

Abstract: As a Fast algorithm of Discrete Fourier Transform (DFT), Fast Fourier Transform (FFT) can quickly analyze discrete signal spectrum and is widely used in communication, radar, medical imaging ...

Over at Quanta Magazine [Shalma Wegsman] asks What Is the Fourier Transform? [Shalma] begins by telling you a little about Joseph Fourier, the French mathematician with an interest in heat propagation ...
