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 ...

As we listen to a piece of music, our ears perform a calculation. The high-pitched flutter of the flute, the middle tones of the violin, and the low hum of the double bass fill the air with pressure ...

Package fft provides an efficient radix-2 fast discrete Fourier transformation algorithm in pure Go. This code is much faster than existing FFT implementations and uses no additional memory. The ...

This repository provides a Python implementation of the Pseudo-Polar Fourier Transform (PPFT) in both 2D (PPFT2D) and 3D (PPFT3D), based on the methods presented in the following papers: ...
