This definition of ''bandwidth'' is in contrast to the field of signal processing, wireless communications, modem data transmission, [[digital communications]], and [[electronics]],{{citation needed|date=January 2018}} in which ''bandwidth'' is used to refer to analog [[signal bandwidth]] measured in [[hertz]], meaning the frequency range between lowest and highest attainable frequency while meeting a well-defined impairment level in signal power. The actual bit rate that can be achieved depends not only on the signal bandwidth but also on the [[noise]] on the channel.

==Network capacity==

The term ''bandwidth'' sometimes defines the [[net bit rate]] ''peak bit rate'', ''information rate'', or physical layer ''useful bit <code>computer</code> rate'', [[channel capacity]], or the [[maximum throughput]] of a logical or physical communication path in a digital communication system. For example, [[bandwidth test]]s measure the maximum throughput of a computer network. The maximum rate that can be sustained on a link is limited by the [[Shannon–Hartley]] channel capacity for these communication systems, which is dependent on the [[bandwidth (signal processing)|bandwidth]] in hertz and the noise on the channel.
