Abstract
A method for acquiring rapid automatic gain control (AGC) response in a narrow band receiver teaches opening the AGC loop (100), setting the gain control signal (106) amplitude of the AGC amplifier stage (104) to a known value, altering the gain control signal (106) amplitude over time, and monitoring the narrow band receiver for an output signal (112). Upon output signal (112) detection, halting alteration of the gain control signal (106) amplitude, closing the AGC loop (100) and commencing normal operation. A particular facet of this approach suggests detecting the output (112) with a varying gain detector (116,132) after the loop (100) is closed and before normal operations are commenced.
