Title
(EN) PASSIVE ANALOG FILTER FOR NETWORK INTERFACE
(FR) FILTRE ANALOGIQUE PASSIF POUR INTERFACE DE RESEAU
Abstract
(EN)
A network interface for receiving both high speed signals and low speed signals includes a passive filter manufactured entirely from passive electronic elements. The filter filters the low speed signal when a low speed signal is received, and does not distort a high speed signal transmitted to an encoder/decoder device when a high speed signal is received.
(FR)
La présente invention concerne une interface de réseau destinée à recevoir à la fois des signaux à vitesse élevée et des signaux à faible vitesse, et comportant un filtre passif entièrement fabriqué à partir d'éléments électroniques passifs. Le filtre filtre le signal à faible vitesse lorsqu'il reçoit un signal à faible vitesse et ne déforme pas un signal à vitesse élevée, transmis à un dispositif codeur/décodeur, lorsqu'il reçoit un signal à vitesse élevée.
