Qu'est-ce (qui) est baseband - définition

RANGE OF FREQUENCIES OCCUPIED BY AN UNMODULATED SIGNAL

Baseband technology; Baseband signal; Low-pass equivalent; Equivalent baseband signal; Equivalent lowpass signal; Baseband equivalent signal; Baseband Signal; Base band; Baseband signaling; Baseband channel; Equivalent baseband model; Baseband transmission

baseband

A transmission medium through which digital signals are sent without frequency shifting. In general, only one communication channel is available at any given time. Ethernet is an example of a baseband network. See also broadband. (1995-02-22)

Baseband

In telecommunications and signal processing, baseband is the range of frequencies occupied by a signal that has not been modulated to higher frequencies.Jeff Rutenbeck, Tech Terms: What Every Telecommunications and Digital Media Professional Should Know, p.

Baseband processor

IN SMARTPHONES AND OTHER RADIO NETWORK INTERFACE DEVICES

Baseband Processor; Mobile baseband; Baseband chip

A baseband processor (also known as baseband radio processor, BP, or BBP) is a device (a chip or part of a chip) in a network interface controller that manages all the radio functions (all functions that require an antenna); however, this term is generally not used in reference to Wi-Fi and Bluetooth radios. A baseband processor typically uses its own RAM and firmware.

Baseband

In telecommunications and signal processing, baseband is the range of frequencies occupied by a signal that has not been modulated to higher frequencies. Baseband signals typically originate from transducers, converting some other variable into an electrical signal. For example, the electronic output of a microphone is a baseband signal that is analogous to the applied voice audio. In conventional analog radio broadcasting, the baseband audio signal is used to modulate an RF carrier signal of a much higher frequency.

A baseband signal may have frequency components going all the way down to DC, or at least it will have a high ratio bandwidth. A modulated baseband signal is called a passband signal. This occupies a higher range of frequencies and has a lower ratio and fractional bandwidth.
