The Algorithm The FFT can be factored in a variety of different ways; each way results in a different algorithm. The most common factorization is the Cooley-Tukey algorithm, which recursively factors ...

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 ...

The FFT algorithm works for both real or complex input signals, but the resulting frequency data is always complex. Most real-world signals have no imaginary components, and these purely real signals ...

We present a modifi- cation to this algorithm that removes the need for a dampening parameter and leads to an increase in valuation convergence. The use of the FFT algorithm allows us to employ a wide ...

MIT researchers could speed up file compression using an improved Fourier transform algorithm A group of MIT researchers believe they’ve found a way to speed up audio, video, and image ...

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 ...

What is The Goertzel Algorithm? The Goertzel algorithm can perform tone detection using much less CPU horsepower than the Fast Fourier Transform, but many engineers have never heard of it. This ...
