When James Cooley and John Tukey introduced the Fast Fourier transform in 1965, it revolutionized signal processing and set us on course to an array of technological breakthroughs. But today’s ...

A few years ago, [Artem] learned about ways to focus sound in an issue of Popular Mechanics. If sound can be focused, he reasoned, it could be focused onto a plane of microphones. Get enough ...

High-speed fast Fourier transform (FFT) cores are an essential requirement for any real-time spectral-monitoring system. As the demand for monitoring bandwidth grows in pace with the proliferation of ...

Issued 17 th April 2002 - RF Engines Limited (RFEL), the Isle of Wight, UK -- based signal processing specialist, has released details of its first product in its vectisâ„¢ family of multi-radix ...

Patrick Flandrin president of the association GRETSI. The notion of “signal processing” might seem like something impenetrably complex, even to scientists. However, the fact is that most of them have ...

Design linear discrete-time systems and filters and analyze their behavior. Represent continuous-time signals and linear systems in discrete time, so that such signals can be recovered in continuous ...

Signal processing is a multidisciplinary field concerned with the analysis, transformation, and interpretation of signals—functions that convey information about physical phenomena. At its core, ...

I’m out traveling this week, so my good buddy Darren McCarthy, an RF guru here at Tektronix, is going to fill in for me. My university math teacher always told me (in a thick Russian accent) that when ...
