A

ASYNCHRONOUS

The teletypewriter operation where the transmitter and receiver do not operate continuously [17].


ASYNCHRONOUS ORBIT

One where the satellite does not rotate or move at the same speed as the
earth [17].


ATDS

An abbreviation for the airborne tactical data system [17].

atr

A tube that isolates the transmitter from the antenna and receiver. Used in conjunction with a tr tube [18].


ATTENUATION

The ability of a filter circuit to reduce the amplitude of unwanted frequencies to a level below that of the desired output frequency [9].


ATTRACTION

The force that tends to make two objects approach each other. Attraction exists between two unlike magnetic poles (north and south) or between two unlike static charges [1].


AUDIO AMPLIFIER

An amplifier designed to amplify frequencies between 15 hertz (15 Hz) and 20
kilohertz (20 kHz) [8].


AUDIO-FREQUENCY-TONE SHIFT

A system that uses amplitude modulation to change dc mark and
space impulses into audio impulses [17].


AUTOMATIC GAIN CONTROL

A circuit used to vary radar receiver gain for best reception of signals that have widely varying amplitudes [18].


AUTOMATIC TRACKING

Tracking done by equipment that compares the direction of the antenna axis
and the direction of the received signal and uses the difference (error) signal to reposition the antenna [17].
