If the original signal contains frequency components greater than half of the sampling (Nyquist) rate, then the original signal and the alias will sum to create an error, which is a type of distortion ...

Optical signal transmission can be significantly improved by limiting the wavelength of transmitted signals. Fiber Bragg grating (FBG) is a technique widely used in optical communication, sensing, and ...

San Jose, CA — January 9, 2004 — Fairchild Semiconductor announces the FMS6418A, a highly integrated, triple video driver that is selectable for High Definition (HD) or Standard Definition (SD) signal ...

A unique filtering technology that combines light (photons) and sound (phonon) waves on a single chip is expected to detect radar and communications frequencies better than conventional electronics. A ...
