signal processing

Aside from all of the other important background noise that makes our cellphones run, there's something called the fast Fourier transform running on it, too. The FFT, as it is known, is a signal-processing algorithm that you use more…

The age-old parable of the tortoise and the hare seems to have implications in the world of signal processing. Certain signal processing tasks, such as precisely selecting frequency channels, require slower data transfer rates. Optical…
