Baseband meaning

Electronic data in their original form. Baseband refers to analog or digital data before being intermixed with other data. See multiplexing and modulation.For ExampleThe output of an analog microphone is baseband. When an FM station's carrier frequency is stripped away in the radio (demodulated), the original audio signal that you hear is the baseband signal. See frequency modulation.Ethernet transmission is considered baseband, because signals are not intermixed and occupy the full bandwidth of the line. In fact, "base" is part of the Ethernet version name (see 10Base-T and 100Base-T).When a compressed digital audio signal such as MP3 is transcoded to another format, it is decompressed back to the original bit rate (the baseband signal) before it is compressed into the new format (for a specific example, see aptX). See baseband processor.

A single-channel transmission system, i.e., a transmission system that supports a single transmission at any given time. All contemporary wired local area networks (LANs) are baseband. See also broadband, channel, and LAN.

(telecommunications) The frequency range occupied by a message signal prior to modulation.

(telecommunications, noun adjunct) A method of transmission in which only one frequency channel is used at a time.

(electronics) A device using baseband transmission.
