The Fourier transform underpins so much of our technological lives, in most cases probably without our realising it. The ability to mathematically split a waveform into its frequency components and ...
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 ...
A new algorithm performs Fourier transforms using a minimal number of samples. The fast Fourier transform, one of the most important algorithms of the 20th century, revolutionized signal processing.
When you listen to digital music, the harmonies and chords that you hear have probably been reconstructed from a file that stored them as components of different frequencies, broken down by a process ...
To make a direct comparison between Fourier and Zernike reconstructions of ocular wavefronts using a newly available analytical theory by which Fourier coefficients can be converted to Zernike ...
American Journal of Mathematics, Vol. 131, No. 2 (Apr., 2009), pp. 277-311 (35 pages) We prove sharp endpoint results for the Fourier restriction operator associated to nondegenerate curves in ${\rm{R ...
San Jose, Calif. – RF Engines Ltd. has made a substantial intellectual-property (IP) business out of creating signal-processing building blocks that are crafted for implementation in FPGAs. The ...
