Title (EN) TRANSFORMERLESS INTERFACE FOR MODEM
(FR) ARCHITECTURE HYBRIDE D'INTERFACE À LIGNE DIRECTE DANS UN MODEM
Abstract: front page image
(EN)A modem couples to a transmission line without a coupling transformer and is capable of reducing common mode interference received from the transmission line. Suppression circuitry provides desired suppression of common mode interference. Methods for reducing and eliminating common mode interference are also described.
(FR)Dans le cadre de cette invention, un modem, qui se couple à une ligne de transmission sans transformateur de couplage, est capable de réduire le brouillage de mode commun émanant de la ligne de transmission. Les circuits de suppression permettent d'éliminer, de façon satisfaisante, ce brouillage de mode commun. L'invention porte également sur des procédés permettant de réduire et d'éliminer le brouillage de mode commun.
