- Amplitude modulation (AM)
- A method user to impress information signals on a sine wave by varying
- its strength according to patterns by the information signals.
- Analog transmission
- The transmission of information by means of a continuously varying
- electrical signal.
- Carrier
- A continuous frequency signal that is modulated by the patterns
- produced by a separate information signal.
- Bit
- The smallest element of a computer code which given a numerical value
- of either 1 or 0. A single electrical pulse in a group of pulses.
- Baseband signaling
- The transmission of an analog signal at its original frequency. The
- direct transmission of unmodulated digital pulses over a comm. line.
- Asynchronous transmision
- A method of transmitting computer data one character at a time. The
- length of time between character is variable.
- Attenuation
- A reduction in the strength of an electrical signal that occurs during
- transmission
- bps (bits per second)
- The measurement of the rate at which digital information signals are
- transmitted.
- Address
- Any goup of bits that identifies a network node as a separate,
- identifiable location.
- Bandwidth
- The range of frequencies of an electromagnetic energy form measured
- from the lowest to the highest frequencies.
- Broadband link
- A transmission channel with a wide frequency range that is divided into
- separate communication channels.
- Bisync
- A common name for Binary Synchronous Communications Control, a half-
- duplex communications line.
