Threshold setting using piecewise linear approximation for channel diagnostic systems

摘要

A method and apparatus for detecting faults in cables. The invention comprises computing a plurality of thresholds representing a corresponding plurality of values of reflections in the cable; comparing a received reflection to a given threshold; if the received reflection value is greater than the given threshold value, then determining the location of the cable fau and if the received reflection is not greater than the given threshold value, then taking no further action.
