In broadband networks, the capacity of the cable is divided into channels, which can transmit many simultaneous signals. Broadband networks may transmit a mixture of digital and analog signals, as will be the case in hybrid fiber/coax interactive cable television networks.

Baseband is the name given to a transmission method in which the entire bandwidth (the rate at which information travels through a network connection) is used to transmit just one signal. Baseband is a cheaper method than broadband and is typically used for shorter distances of transmission.

Baseband is an adjective that describes signals and systems whose range of frequencies is measured from 0 to a maximum bandwidth or highest signal frequency; it is sometimes used as a noun for a band of frequencies starting at 0. It can often be considered as synonym to lowpass, and antonym to passband.
