FILTRE TRANSVERSE ELECTRIQUE A FONCTIONNEMENT OPTIQUE.

摘要

The invention describes a programmable transversal filter for adaptive filtering of signals with a very broad passband. The signals to be filtered modulate one or more optical carriers (F1) in a modulator (mod). Each carrier is distributed over several channels by a divider (DIV). Each channel is equipped with a delay line (CR1 to CRn). These channels are then summated after being correctly delayed, and a coefficient characteristic of the signal being detected is assigned to them. Application in processing broadband signals.
