ABSTRACT:
An automatic gain control circuit and system for using same provides linear attenuation response to input data signals of multiplexed frequencies of high and low signal amplitudes to eliminate frequency intermodulation products generated by the data signals of high amplitude from interfering with the reception of the proper data signals by a tuned receiver communicating with the automatic gain control circuit.
