Abstract

ECUALIZADOR ADAPTATIVO DE RETARDO. LA SEÑAL DE LLEGADA ES APLICADA A UN AMPLIFICADOR (11), DE SEÑAL DE SALIDA DE AMPLITUD CONSTANTE, Y QUE ALIMENTA DIRECTAMENTE UN CIRCUITO DE SUSTRACCION (12), E INDIRECTAMENTE A TRAVES DE UN CIRCUITO DE RETARDO LINEAL (13). LA SALIDA DEL CIRCUITO DE SUSTRACCION PASA A TRAVES DE UN FILTRO DE PASO BAJO (16), CUYA SALIDA FORMA LA SALIDA DEL ECUALIZADOR, A UN CONFORMADOR DE IMPULSOS (17). DESDE ESTE SE APLICA A UN CIRCUITO DE ALGORITMO DE ERROR DE ECUALIZACION (18) Y AL CIRCUITO DE EXTRACCION DE RELOJ (19). DE APLICACION EN SISTEMAS DE TRANSMISION DIGITALES.
