Abstract
PARA UNA REGULACION DIGITAL DEPENDIENTE DE SEÑALES DE RECEPCION DIGITALES DE UN AMPLIFICADOR DE RECEPCION REGULABLE DIGITALMENTE, UN DISPOSITIVO DE CONECTORES POSEE UN ECUALIZADOR (K1/K2) PARA LAS SEÑALES POSITIVAS Y NEGATIVAS (ES) DE RECEPCION, AMPLIFICADAS CON EL FACTOR AMPLIFICADOR, CUYAS SALIDAS RESPECTIVAS, POR MEDIO DE UNA RED DE ENCHUFE REGENERATIVO (RSN1/RSN2), SON RECONDUCIDAS A UNA ENTRADA DEL DISPOSITIVO CORRESPONDIENTE DE ECUALIZACION. POR MEDIO DE LAS REDES CONECTADAS DE REACOPLAMIENTO (RSN1/RSN2) EL NIVEL DE SEÑAL, EN CADA UNA DE LAS ENTRADAS DE ECUALIZACION, EN DEPENDENCIA DE LAS SEÑALES, MUESTRA VALORES DE ECUALIZACION DIFERENCIALES (K1,K2) EN LA SALIDA DE UN DISPOSITIVO ECUALIZADOR. SIEMPRE QUE EL NIVEL DE LA SEÑAL DE RECEPCION (ES) SUPERA A UNO DE LOS VALORES DE ECUALIZACION SE DESCIENDE UN GRADO EN UN DISPOSITIVO CONTADOR (Z) NO LINEAL QUE REGISTRA EL GRADO DE AMPLIFICACION. TRAS CADA BLOQUE DE DATOS TRANSMITIDOS, EL DISPOSITIVO CONTADOR (Z), RETORNA A LA SITUACION MAS ELEVADA DEL CONTADOR. POR MEDIO DE UN CIRCUITO MULTIVIBRADOR MULTIESTABLE, SUSCEPTIBLE DE CONTROLAR LA EMISION DE BLOQUES DE DATOS RETORNABLE AL IMPULSO TRIGGER, MEDIANTE LA REPETICION DEL IMPULSO TRIGGER QUE UTILIZA LA SEÑAL DE RECEPCION, CON EL CORRESPONDIENTE TIEMPO DE PARADA.
