COAXIAL CABLE

Cable in which the center conductor is separated from an outer conductor by a
dielectric material; used in RF transmission [4].

COAXIAL LINE

A type of transmission line that contains two concentric conductors [10].

CODE

In teletypewriter operation, code is a combination of mark and space conditions representing symbols, figures, or letters [17].

COEFFICIENT OF COUPLING

An expression of the extent to which two inductors are coupled by
magnetic lines of force. This is expressed as a decimal or percentage of maximum possible coupling and represented by the letter K [2].

COHERENCE

A definite phase relationship between two energy waves, such as transmitted frequency and reference frequency [18].

COHERENT

Radiation on one frequency [17].

COHERENT OSCILLATOR

In cw radar an oscillator that supplies phase references to provide coherent
video from target returns [18].

COIL

An inductive device made by looping turns of wire around a core [2].

COLD-CATHODE TUBE

A gas-filled electron tube that conducts without the use of filaments. Cold-
cathode tubes are used as voltage regulators [6].

COLLECTOR

The element in a transistor that collects the current carriers [7].
