Abstract
A technique for analyzing a signal received from a recording medium. An input signal is received from the recording medium and analyzed in order to determine the location of errors within the input signal. The portion of the input signal determined to have an error is displayed. The analysis technique is selected from the group consisting of comparing the input signal with a reference signal, comparing a confidence factor indicative of the ease with which an apparatus that performs a channel emulation is able to select between alternate results for a portion of the input signal with a confidence factor indicative of the ease with which the apparatus that performs a channel emulation is able to select between alternate results of a portion of a reference signal, comparing the confidence factor indicative of the ease with which the apparatus that performs a channel emulation is able to select between alternate results of a portion of said input signal with a predetermined threshold, and comparing a Non Return to Zero (NRZ) component of the input signal with a stored NRZ signal.
