A
ASYNCHRONOUSThe teletypewriter operation where the transmitter and receiver do not operate continuously [17]. |
ASYNCHRONOUS ORBITOne where the satellite does not rotate or move at the same speed as the earth [17]. |
ATDSAn abbreviation for the airborne tactical data system [17]. |
atrA tube that isolates the transmitter from the antenna and receiver. Used in conjunction with a tr tube [18]. |
ATTENUATIONThe ability of a filter circuit to reduce the amplitude of unwanted frequencies to a level below that of the desired output frequency [9]. |
ATTRACTIONThe 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 AMPLIFIERAn 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 CONTROLA circuit used to vary radar receiver gain for best reception of signals that have widely varying amplitudes [18]. |
AUTOMATIC TRACKINGTracking 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]. |
