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         
  • Baseband processor SiTel SC14434
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.
Line code         
  • An example of [[bipolar encoding]], or AMI.
  • An example of [[biphase mark code]]
  • An arbitrary bit pattern in various binary line code formats
  • An example of [[MLT-3 encoding]]
  • Encoding of 11011000100 in [[Manchester encoding]]
PATTERN USED WITHIN A COMMUNICATIONS SYSTEM TO REPRESENT DIGITAL DATA
Line encoding; Line coding; Phase shaped binary transmission; Baseband modulation; Digital baseband modulation; Line Code; Encoding scheme; Digital frequency modulation
In telecommunication, a line code is a pattern of voltage, current, or photons used to represent digital data transmitted down a communication channel or written to a storage medium. This repertoire of signals is usually called a constrained code in data storage systems.

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.
