Abstract
Display of signals containing inter-symbol interference (ISI). An input signal is modeled as comprising an ideal signal plus ISI plus error. In a first embodiment of the invention, an error signal and an ideal signal are derived from the input signal. The ideal signal is combined with the error signal producing an ideal signal with errors. In a second embodiment of the invention, a first signal comprising the ideal signal plus ISI plus error is derived. A second signal comprising only ISI is derived, and subtracted from the first signal, producing a signal containing the ideal signal plus error.
