Detection

nounStandard termTelecom & IT

The extraction of meaningful information or baseband signals from a modulated carrier wave.

The process of recovering the original modulating signal (such as audio, video, or data) from a received radio-frequency carrier wave. In radio and telecommunications, a detector circuit rectifies and filters the high-frequency alternating current, leaving only the low-frequency intelligence that was originally transmitted.
