Abstract

EXISTEN SISTEMAS DE TRANSMISION MULTIPLEX DE TIEMPO EN LOS QUE LAS SEÑALES DIGITALES, FORMADAS POR BLOQUES SUCESIVOS ASINCRONICOS CON RELACION A LA TRAMA, CUYOS PRINCIPIOS DE BLOQUE SE MARCAN CON UNA PALABRA DE SINCRONIZACION, SE INSERTAN EN LA TRAMA. LA VARIACIONES DEL RELOJ DE LAS PALABRAS DE SINCRONIZACION, ES DECIR LA FLUCTUACION DE FASE DEL TIEMPO DE ESPERA, PRODUCIDA SE REDUCE CON UN CIRCUITO, QUE GENERA A PARTIR DEL RELOJ DEL TREN DE PALABRAS DE SINCRONIZACION RECIBIDO UNA SEÑAL DE SINCRONIZACION (SY), QUE POSEE UNA VARIACION DE RELOJ MENOR QUE EL RELOJ DEL TREN DE PALABRAS DE SINCRONIZACION RECIBIDO. SEGUN EL INVENTO, CONTIENE UN DISPOSITIVO DE MEDIDA, QUE MIDE LA SEPARACION (N) EN EL TIEMPO DE LAS PALABRAS DE SINCRONIZACION, UN FILTRO (F), QUE FORMA UN VALOR MEDIO (N'') A PARTIR DE (N) Y UN GENERADOR DE SEÑALES (S), QUE FORMA PARTIR DEL VALOR MEDIO (N'') UNA SEÑAL DE SINCRONIZACION (SY) CUYO PERIODO DE RELOJ ES IGUAL AL VALOR MEDIO (N'').
