Abstract

A line build out comprises a control voltage mechanism for applying a control voltage to a tuning diode or varactor. The control voltage is generated so as to be indicative of the length of a cable over which the signal has traveled. The capacitance of the tuning diode or varactor is changed according to the control voltage. A resistor is connected to the cathode of the tuning diode or varactor and a capacitor is connected to the anode of the tuning diode or varactor. A signal can be measured at the cathode which corresponds to the incoming signal and has been attenuated by frequency roll-off in accordance with the length of the cable over which the signal has traveled. In this way, attenuation for signals over cables of various length can be equalized in a manner which not only takes into account the length of the cable, but also the frequency of the signal.
