bandwidth
- The range of frequencies that an electronic signal occupies on a given transmission medium. Any digital or analog signal has a bandwidth. In digital systems, bandwidth is often expressed as data speed in bits per second. In analog systems, bandwidth is expressed in terms of the difference between the highest-frequency signal component and the lowest-frequency signal component. For example, a typical voice signal on an analog telephone line has a bandwidth of about 3 kHz. An analog television (TV) broadcast video signal has a bandwidth of 6 MHz, some 2,000 times as wide as the telephone signal. As a general rule, systems with more bandwidth can carry more information.
- The range of wavelengths or frequencies to which an antenna is sensitive.
- In communications and computing, the rate at which data is transferred, usually measured in bits (or megabits or gigabits) per second.
