A baseband channel or lowpass channel (or system, or network) is a communication channel that can transfer frequencies that are very near zero. [4] Examples are serial cables and local area networks (LANs), as opposed to passband channels such as radio frequency channels and passband filtered wires of the analog telephone network.
According to the most common definition of a digital signal, both baseband and passband signals representing bit-streams are considered as digital transmission, while an alternative definition only considers the baseband signal as digital, and passband transmission of digital data as a form of digital-to-analog conversion.

In this context, baseband is the term's antonym, referring to a single channel of analog video, typically in composite form with separate baseband audio. [21] The act of demodulating converts broadband video to baseband video. Fiber optic allows the signal to be transmitted farther without being repeated.
A base transceiver station (BTS) or a baseband unit [1] (BBU) is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless Internet connectivity, or antennas mounted on buildings or telecommunication towers.
Classic Ethernet is a family of 10 Mbit/s Ethernet standards, which is the first generation of Ethernet standards. In 10BASE-X, the 10 represents its maximum throughput of 10 Mbit/s, BASE indicates its use of baseband transmission, and X indicates the type of medium used.
In the public switched telephone network (PSTN), in-band signaling is the exchange of call control information within the same physical channel, or within the same frequency band, that the message (the callers' voice) is using.
This computer was the basis for all of Apple’s modern computers that followed. It launched in 1984, and while it seems like a bulky monstrosity compared to today’s sleek laptops, collectors ...
the line-coded signal (the baseband signal) undergoes further pulse shaping (to reduce its frequency bandwidth) and then is modulated (to shift its frequency) to create an RF signal that can be sent through free space.
