AMBIENT TEMPERATUREThe surrounding temperature such as the temperature of air surrounding a conductor in a compartment or within a piece of equipment [4]. | ||
AMBIGUOUS RETURNSEchoes that exceed the prt of a radar and appear at incorrect ranges [18]. | ||
AMMETERAn instrument for measuring the amount of electron flow (in amperes) [1] [3] [6]. | ||
AMPEREThe basic unit of electrical current [1]. | ||
AMPERE-TURN The magnetomotive force developed by 1 ampere of current flowing through a coil of one turn [8]. | ||
AMPLIDYNEA special dc generator in which a small dc voltage applied to field windings controls a large output voltage from the generator. In effect, an amplidyne is a rotary amplifier that often times produces gain of approximately 10,000 [5]. | ||
AMPLIFICATION(1) The process of enlarging a signal in amplitude (as of voltage or current) [8]. (2) The ratio of output magnitude to input magnitude in a device that is intended to produce an output that is an enlarged reproduction of its input [6] [7]. | ||
AMPLIFICATION FACTORThe voltage gain of an amplifier with no load on the output [6] [7]. | ||
AMPLIFIERAMPLIFIER—The device that provides amplification (the increase in current, voltage, or power of a signal) without appreciably altering the original signal [7] [8]. | ||
