| COAXIAL CABLE. Cable in which the center conductor is separated from an outer conductor by a dielectric material; used in RF transmission. A longer description may be found in the Radar section; Coaxial Cable Definition. Manufacturers of Coax, Twinax, Triax Cable |
 Coax Cable |
COAXIAL LINE. A type of transmission line that contains two concentric conductors.
CODE. Code is a combination of mark and space conditions representing symbols, figures, or letters.
CODEC: Acronym for coder-decoder. An assembly consisting of an encoder and a decoder in one piece of equipment. A circuit that converts analog signals to digital code and vice versa. An electronic device that converts analog signals, such as video and voice signals, into digital form and compresses them to conserve bandwidth on a transmission path. Note: Codecs in this sense are used in this sense for video conferencing systems. Manufacturers of CODEC ICs.
CODER-DECODER: See Codec.
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.
COHERENCE. A definite phase relationship between two energy waves, such as transmitted frequency and reference frequency.
COHERENT. Radiation on one frequency.
COHERENT OSCILLATOR. An oscillator that supplies phase references. Radar Dictionary
COIL. An inductive device made by looping turns of wire around a core. [Coil manufacturers]
Through-Hole Coils
COLD-CATHODE TUBE. A gas-filled electron tube that conducts without the use of filaments. Cold-cathode tubes are used as voltage regulators.
COLLECTOR. The element in a transistor that collects the current carriers. [Transistor Definitions, Manufacturers of Transistors]
COLLECTOR-INJECTION MODULATOR. The transistor equivalent of a plate modulator. Modulating voltage is applied to a collector circuit.
COLLINEAR ARRAY. An array with all the elements in a straight line. Maximum radiation is perpendicular to the axis of the elements.
COMBINATION ARRAY. An array system that uses the characteristics of more than one array.
COMBINATION CIRCUIT. A series-parallel circuit. [Antenna Terms]
COMBINATION PEAKING. A technique in which a combination of peaking coils in series and parallel (shunt) with the output signal path is used to improve high-frequency response.
COMMERCIAL-OFF-THE-SHELF. [COTS] item is defined as any item that can be purchased and does not need to be designed. [Detailed Definition of COTS]
COMMON BASE. The Base element is common to both the input and output circuit, normally grounded. See Transistor Terms.
COMMON-BASE DETECTOR. An amplifying detector in which detection occurs in the emitter-base junction and amplification occurs at the output of the collector junction.
COMMON CARRIER. In the telecommunications area, the term used to describe a telephone company.
COMMON COLLECTOR. See Transistor Terms.
COMMON EMITTER. See Transistor Terms. [Common Emitter BJT Schematics]
COMMON-EMITTER DETECTOR. Often used in receivers to supply detected and amplified output. The emitter-base junction acts as the detector.
COMMON IDENTITIES LAW. In Boolean algebra this law states that anytime the expression A(A + B) = AB or A + AB = A + B appears, it can immediately be simplified to AB without going through the process of using the distributive law, complementary law, or the law of union to simplify.
