A

AUTOMATIC VOLUME/GAIN CONTROL

A circuit used to limit variations in the output signal strength of a receiver [17].

 Keyword(s): AUTOMATIC VOLUME/GAIN CONTROL

AVALANCHE EFFECT

A reverse breakdown effect in diodes that occurs at reverse voltages beyond 5
volts. The released electrons are accelerated by the electric field, which results in a release of more electrons in a chain or "avalanche" effect [7].

 Keyword(s): AVALANCHE EFFECT

AVERAGE POWER

(1) The peak power value averaged over the pulse-repetition time [12]. (2) Output power of a transmitter as measured from the start of one pulse to the start of the next pulse [18].

 Keyword(s): AVERAGE POWER

AVERAGE VALUE

The average of all the instantaneous values of one-half cycle of alternating
current [2].

 Keyword(s): AVERAGE VALUE

AWG

The standards adopted in the United States for the measurement of wire sizes [4].

 Keyword(s): AMERICAN WIRE GAUGE (AWG)

AXIS

A straight line, either real or imaginary, passing through a body around which the body revolves
[15].

 Keyword(s): AXIS

AZIMUTH

Angular measurement in the horizontal plane in a clockwise direction [18].
 Keyword(s): AZIMUTH

B

BACK RESISTANCE

The larger resistance value observed when you are checking the resistance of a
semiconductor [16].

 Keyword(s): BACK RESISTANCE

BALANCED MIXER

A waveguide arrangement that resembles a T and uses crystals for coupling the
output to a balanced transformer [18].

 Keyword(s): BALANCED MIXER

BALANCED PHASE DETECTOR

A circuit that controls the oscillator frequency (afc) [17].
 Keyword(s): BALANCED PHASE DETECTOR
