In a group of waves that have slightly different individual frequencies, the time required for any defined point on the envelope (i.e., the envelope determined by the additive resultant of the group of waves) to travel through a device or transmission facility.
Industry:Telecommunications
In a half-duplex circuit, the time required to reverse the direction of transmission from transmit to receive or vice versa.
Industry:Telecommunications
In a hollow metallic waveguide, a longitudinally movable metallic plane surface that reflects essentially all the incident energy. Note: A piston is used for tuning, e.g., fine-tuning a resonant cavity. Synonym plunger.

Industry:Telecommunications
In a land or maritime convoy, communications (a) that is among the elements of the convoy, (b) includes radio, visual, and sound transmissions, (c) in which radio intervehicle or intership communications are usually by radiotelephone using the receipt method of operation, (d) in which the convoy commander vehicle or ship usually has the net-control station aboard and (e) that usually use a single assigned frequency.
Industry:Telecommunications
In a language, the relationships among characters or groups of characters, independent of their meanings or the manner of their interpretation and use. 2. The structure of expressions in a language. 3. The rules governing the structure of a language. 4. In a language, the relationship among symbols. Note: In computer languages, as in all artificial languages, syntax is developed, and usually described, before their use begins. In natural languages, syntax is developed, and sometimes never described, after use has begun.
Industry:Telecommunications
In a laser, the driving current corresponding to lasing threshold.
Industry:Telecommunications
In a layered open communications system, a specified subset of the services, functions, and protocols included in a given layer. 2. In the Open Systems Interconnection--Reference Model, a subdivision of a given layer, e.g., a conceptually complete group of the services, functions, and protocols included in the given layer.
Industry:Telecommunications
In a lightning protection subsystem, the conductor connecting the air terminal or overhead ground wire to the earth electrode subsystem.
Industry:Telecommunications
In a line or circuit, the dc potential difference between ground and the common return.
