Something called the fast Fourier transform is running on your cell phone right now. The FFT, as it is known, is a signal-processing algorithm that you use more than you realize. Alexander Stoytchev – ...

However, on closer examination, there are features of both algorithms that suggest at least a conceptual similarity. This note is written in a heuristic spirit and is intended to offer a motivation ...

Researchers from MIT have developed a new algorithm designed to improve on the fast Fourier transform (FFT) in a large number of cases. The discovery paves the way for smartphones to wirelessly ...

Engineers have solved a 50-year-old puzzle in signal processing. They've formulated the 'inverse chirp z-transform,' an algorithm related to one that's running on your cell phone right now. It ...

RF Engines demonstrated industry leading Fast Fourier Transform (FFT) cores. HyperSpeed and HyperLength FFT s provide silicon efficient implementations of the FFT algorithm for spectral analysis, and ...

Because the FFT is inherently a block-oriented algorithm, the FFT operates most efficiently when quick access to all input and output samples is supported by a freely-addressable RAM. However, this ...

In this paper, the authors: Showcase modelling benefits of Lévy processes and the FFT in gas storage valuation. Derive unique results based on a Mean Reverting Variance-Gamma (MRVG) process. Present ...

In this video from PyData Seattle 2015, William Cox from Distil Networks presents: An Intuitive Introduction to the Fourier Transform and FFT. The “fast fourier transform” (FFT) algorithm is a ...
