ABSTRACT:
Apparatus for correcting attenuation distortion in low frequency cable carrying a base-band signal from a transmitter to a receiver is described. A measuring device produces an indicating signal having a value dependent on the peak value of the base-band signal appearing in the region of the receiver. The receiver contains an amplifier, the gain of which is controlled by a RC element. The indicating signal is used to regulate the gain of the amplifier so that the cable and the amplifier together produce a substantially constant attenuation characteristic within a given low frequency range.
