Previous section of 'A' terms and definitions

AND Gate
AND GATE. An electronic gate whose output is energized only when every input is in its prescribed state. An AND gate performs the function of the logical "AND"; also called an AND circuit. A binary circuit, with two or more inputs and a single output, in which the output is a logic 1 only when all inputs are a logic 1 and the output is a logic 0 when any one of the inputs is a logic 0. [IC Manufacturers]

ANGLE. Refer to this page for terms relating to Angle Definitions.

ANGSTROM. 10-10 meter.

ANGSTROM UNIT. The unit used to define the wavelength of light waves.

ANISOTROPIC. The property of a radiator that allows it to emit strong radiation in one direction.

ANODE. A positive electrode of an electrochemical device (such as a primary or secondary electric cell) toward which the negative ions are drawn. The semiconductor-diode terminal that is positive with respect to the other terminal when the diode is biased in the forward direction.

ANNEAL. To soften and relieve strains in any solid material, such as metal or glass, by heating to just below its melting point and then slowly cooling it. This also generally lowers the tensile strength of the material, while improving its flex life.

ANSI. American National Standards Institute. Acronym.

ANTENNA. A conductor or set of conductors used to radiate RF energy into space or to collect RF energy from space or to do both. [Antenna Manufacturers], [Antenna Terms]

ANTENNA BEAM WIDTH. Width of a radar beam measured between half-power points. [Radar Terms]

ANTENNA COUPLER. A device used for impedance matching between an antenna and a transmitter or receiver.

ANTENNA SYSTEM. Routes RF energy from the transmitter, radiates the energy into space, receives echoes, and routes the echoes to the receiver. [Antenna Tracking Systems]

ANTISEIZE COMPOUND. A silicon-based, high-temperature lubricant applied to threaded components to aid in their removal after they have been subjected to rapid heating and cooling.

ANTITRANSMIT-RECEIVE TUBE (atr). A tube that isolates the transmitter from the antenna and receiver. Used in conjunction with a tr tube.

Next section of "A" definitions and terms

This is a glossary of electronic and engineering terms. A glossary is really about the same as a dictionary without pronunciations, functions, meanings, and syntactical and idiomatic uses. Engineering terms are added on a regular basis.
