Title (EN) REGENERATOR HAVING AUTOMATIC GAIN CONTROL REFERENCED TO A DATA-PATTERN-DEPENDENT PULSE STREAM
(FR) REGENERATEUR AYANT UNE COMMANDE DE GAIN AUTOMATIQUE ASSOCIE A UN FLUX PULSE DEPENDANT DES CONFIGURATIONS DE DONNEES
Abstract: front page image
(EN)A roving reference automatic gain control (AGC) arrangement is used in a regenerator of a pulse code modulation (PCM) transmission system. An adjustable gain circuit (40, 45) receives a sequence of data pulses and produces a data-pattern-dependent input signal (47, 48, 49). A signal channel circuit (55), responsive to the input signal, produces a data-pattern-dependent detected signal. Regeneration circuitry (50, 52), responsive to the input signal, produces a regenerated data-pattern-dependent output signal. A reference channel circuit (62, 65), responsive to the output signal, produces a data-pattern-dependent reference signal. A circuit (70) algebraically combines the detected signal with the reference signal to form a continuously-variable data-pattern-independent gain control signal which is applied (42) to the adjustable gain circuit for controlling the gain thereof.
(FR)Un agencement de commande de gain automatique de reference errant (AGC) est utilise dans un regenerateur d"un systeme de transmission de modulation par impulsions codees (MIC). Un circuit de gain reglable (40, 45) recoit une sequence d"impulsions de donnees et produit un signal d"entree dependant de la configuration des donnees (47, 48, 49). Un circuit de canal de signal (55), sensible au signal d"entree, produit un signal detecte dependant de la configuration des donnees. Un reseau de circuit de regeneration (50, 52), sensible au signal d"entree, produit un signal de sortie regenere dependant de la configuration des donnees. Un circuit de canal de reference (62, 65), sensible au signal de sortie, produit un signal de reference dependant de la configuration des donnees. Un circuit (70) combine algebriquement le signal detecte avec le signal de reference pour former un signal de commande de gain independant de la configuration des donnees et variable de maniere continue qui est applique (42) au circuit de gain reglable pour en commander le gain.
