Abstract
An automatic gain control circuit for use in a multichannel RF system using fiber optic links. The circuit samples the power levels from a number of attenuated RF signals simultaneously and adjusts the gain in all of the channels by the amount required to keep the highest power channel below a predetermined power level determined by the power capacity of the fiber optic link while maintaining the signal strength relationship between the attenuated signals as was existing between the RF input signals.
