TRANSISTOR_AS_ATTENUATOR
Servo-type agc for transistor receivers holds audio output constant despite changes in r-f input. Wideband low-noise amplifier is used in transmission loop, while direct-coupled grounded-emitter amplifier drives detector circuit in feedback loop.-F. Susi, Solving the AGC Di-lemma-Servo System Uses Attenuator, Electronics, 36:29, p 60-62.
