ABSTRACT:
An adaptive cable equalizer (10) includes an input section (12) that receives a radio frequency electrical signal from a cable (14). The input section (12) provides the electrical signal to an equalizing amplifier section (16) that controls an amount of current flow of the electrical signal to an equalizing controller (18). The equalizing controller (18) generates an equalized output signal (21) through a voltage drop which is proportional to a roll-off distortion of the cable (14). The voltage drop is processed by an amplifier (80) and a line receiver (88) to reconstruct the electrical signal in a digital representation of the equalized output signal (21). The voltage drop is also fed to a detector (20) that generates a control signal (23) and a bias signal (25) to adjust the conductivity of the equalizing amplifier section (16). In this manner, adjustments are automatically made in order to provide the equalized output signal (21) regardless of the characteristics of the cable (14).
