Abstract
A receiver that calculates the length of the transmission channel cable based on the receiver parameters is presented. The cable length is calculated based on the gain of an automatic gain control circuit or is based on the multiplier coefficients of an equalizer of the receiver. A comparison between a cable length calculated using the gain from the automatic gain control circuit and a cable length calculated using the multiplier coefficients of the equalizer indicates the quality of the cable.
