ABSTRACT:
An automatic modulation control in a transmitter, comprising an alternating modulation signal source, a modulation signal amplifier, a carrier generator, a modulator for modulating the carrier signal as a function of the output of the modulation signal amplifier, a threshold detector coupled in a direct current manner to the output of the modulation signal amplifier for threshold detecting the modulation signal output, a smoothing circuit for smoothing the threshold detected output, an amplifier for the threshold detected and smoothed output, and a control circuit for controlling the input of the modulation signal to the modulation signal amplifier as a function of the output of the threshold detected output amplifier.
