Method and apparatus for dynamic automatic gain control when pilot signal is lost










Image Number 4 for United States Patent #5742202.

The automatic gain control circuit of the present invention improves upon conventional techniques using a pilot carrier for control by monitoring for the presence of the pilot carrier. If the pilot carrier level is at an undetectable level, it will switch control of the level control section of the automatic gain control circuit to the equivalent thermal setting by means of a switch. The switch connects the output of a temperature-sensing network to a Bode driving circuit that approximates attenuation of a given transmission medium over temperature. The gain setting will therefore be based on an approximation of what the cable losses should be at the detected temperature of the amplifier housing. The present invention provides dynamic gain adjustment, even in the event of pilot carrier signal loss.
