Fractional transforms extend classical integral transforms by introducing a continuous parameter that governs the interpolation between time and frequency domains. The fractional Fourier transform ...

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 ...

Built upon the ubiquitous Fourier transform, the mathematical tools known as wavelets allow unprecedented analysis and understanding of continuous signals. In an increasingly data-driven world, ...

The same engineers, who announced the solution to a 50-year-old puzzle in signal processing last fall, have followed up with more research results. The engineers say their new algorithm is more useful ...

Engineers explore algorithm’s capabilities in special cases ‘on the unit circle’ AMES, Iowa – Iowa State University’s Alexander Stoytchev says it’s one of the “most popular and useful” algorithms ...
