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

We demonstrate an optical fast Fourier transform scheme that provides the necessary computing power to encode lower-bitrate tributaries into 10.8 and 26.0 Tbit s−1 line-rate orthogonal frequency ...

A faster transform means that less computer power is required to process a given amount of information—a boon to energy-conscious mobile multimedia devices such as smart phones.

Creonic's Fast Fourier Transform uses the Cooley-Tukey algorithm internally. The new IP core produces transformed complex samples as output when operating on complex or real signal samples. The ...

That’s Maths: The Fast Fourier Transform dramatically reduced the way computation scales with problem size, making it practicable to solve many problems that could not otherwise be tackled ...

[Simon Inns] just rolled out his latest project, a PIC based spectrum analyzer. He’s using a Fast Fourier Transform routine crafted in C to run as efficiently as possible on the 8-bit chip. The ...

Several algorithms for efficiently evaluating trigonometric polynomials at irregularly spaced points are presented and analyzed. The algorithms can be viewed as approximate generalizations of the fast ...
