Baseband
Updated: 09/12/2023 by Computer Hope
Baseband describes bandwidth and channels (the signal or system frequency). In terms of bandwidth, baseband is the highest frequency (measured in hertz) used by the bandwidth, or the upper bound of the bandwidth.
In terms of a channel, baseband is a type of communication channel that uses frequencies that are close to zero hertz. Serial cables and LANs (local area networks) use baseband channels.
