Abstract

EN UN CIRCUITO DE INTERFAZ DE LINEA PARA SEÑALES DE DATOS BINARIOS SE PROVEE MEDIOS PARA COMPENSAR LAS DISTINTAS LONGITUDES DE LINEA EN EL TRAYECTO DE RECEPCION Y/O TRANSMISION. LA SEÑAL DE UN ECUALIZADOR DE LINEA CONTROLA UN CIRCUITO DE IMPEDANCIA VARIABLE DE TAL MANERA QUE LA ATENUACION DE UNA RED DE ELABORACION DE LINEA SE REDUCE SI EL NIVEL DE SALIDA DEL ECUALIZADOR DESCIENDE POR DEBAJO DE UN CIERTO UMBRAL. UNA RED DE ELABORACION DE LINEA DE TRANSMISION PROVEE UNA FRECUENCIA QUE DEPENDE DE LA ATENUACION DE LOS DATOS BINARIOS POR MEDIO DE UN CIRCUITO DE CONTROL, QUE SUMINISTRA VALORES DE ATENUACION DISCRETOS DE ACUERDO CON UNA PALABRA LOGICA.
