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 ...

AMES, Iowa – Something called the fast Fourier transform is running on your cell phone right now. The FFT, as it is known, is a signal-processing algorithm that you use more than you realize. It is, ...

AMES, Iowa - Iowa State University's Alexander Stoytchev says it's one of the "most popular and useful" algorithms around - even though most of us have never heard of it. But, if you've used a cell ...

Engineers have solved a 50-year-old puzzle in signal processing. They've formulated the 'inverse chirp z-transform,' an algorithm related to one that's running on your cell phone right now. It took ...

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 ...
