Abstract
Apparatus and methods apply pre-emphasis to the phase rather of a signal than to the amplitude of a single. This approach can provide superior pre-emphasis performance than the conventional amplitude pre-emphasis techniques in certain situations, such as when a non-linear slicer is present in the signal path. For example, electrical-to-optical (E/O) and optical-to-electrical (O/E) converters can effectively slice a signal.
