ABSTRACT:
An automatic system for compensating for arbitrary amounts of attenuation introduced by arbitrary lengths of transmission cable being used to communicate multichannel broadband RF signals between a television camera head and a remote camera control station. An attenuation detector is provided which monitors the peak amplitude of the signal in a selected frequency channel of the broadband signal to generate control signals which each change from a first state to a second state at a respective preselected attenuation level. These control signals are used to effect the selective bypassing of an attenuation pad located at the termination of the cable, fixed gain preamplifiers associated with the higher frequency channels of the broadband signal, and a second attenuation pad located at the output of the circuit which transmits the video signal to the viewfinder of the camera head.
