Abstract

A wide band noise extrapolation test system, which may reside within a processor-controlled test head installed in a central office, or as part of test signal generation and processing circuitry of a craftsperson's test set, processes data derived from applying single ended stimuli to a plurality of wirelines. The processing mechanism accurately and reliably identifies the locations and amplitudes of remote noise sources for each of the wirelines, by determining attenuation along and the lengths of the wirelines, and then modifying values of noise measurements in accordance with the determined attenuation and length values, so as to extrapolate the amplitudes of the noise at their identified source locations.
