- the smallest range of frequencies constituting a band within which a particular signal can be transmitted without distortion.
- the transmission capacity of an electronic communications device or system; the speed of data transfer: a high-bandwidth internet connection.
- mental capacity; intelligence: Don't listen to him—he has really low bandwidth.
- a person's capacity to handle or think about more than one thing at the same time: He doesn't have the bandwidth to make those kinds of decisions.
- the range of frequencies within a given waveband used for a particular transmission
- the range of frequencies over which a receiver or amplifier should not differ by more than a specified amount
- the range of frequencies used in a specific telecommunications signal
