Abstract
An intermediate frequency amplifier stage includes a tuned circuit which is shunted by a transistor utilized as an emitter follower, the emitter follower being responsive to the amplitude of a detected signal to lower the 'Q' of the tuned circuit as the amplitude of the detected signal increases and to increase the 'Q' of the tuned circuit as the amplitude of the detected signal decreases, thus effecting the gain of the intermediate frequency amplifier stage inversely respective the amplitude of the detected signal.
