Abstract:
1. An optical signal receiver for receiving an optical signal comprising: a plurality of threshold decision circuits configured to receive an electrical signal representative of said optical signal, each of said threshold decision circuits being configured to sample said electrical signal and to provide an associated threshold decision circuit output in response to a comparison of said signal to an associated threshold level; and an output decision circuit configured to receive each of said threshold decision circuit outputs and output a signal representative of a binary state of said optical signal, wherein said output decision circuit is further configured to apply a selected logic function to said threshold decision circuit outputs for providing said signal representative of said binary state of said optical signal, and wherein said output decision circuit comprises a controller and a look-up table, said controller configured to receive said threshold decision circuit outputs and provide an associated control signal representative of said selected logic function to said look-up table for storing data representative of said selected logic function in said look-up table.
