Abstract
UN CIRCUITO PARA COMPENSAR LA DISTORSION DE TERCER ORDEN CAUSADA POR UN TRANSMISOR EN LA SEÑAL A SER TRANSMITIDA. COMPRENDE UN SUMADOR (1), UN PRE-ECUALIZADOR (2) QUE SIGUE AL SUMADOR (1), UN CIRCUITO DE EVALUACION (4) QUE CONTROLA EL PRE-ECUALIZADOR Y UN GENERADOR DE SEÑAL DE PRUEBA (5). CONECTADO AL PRE-ECUALIZADOR (2) ESTA EL COMPONENTE TRANSMISOR, EN ESTE CASO UN LASER (3). LA SEÑAL (SA) PROPORCIONADA POR EL LASER, SE TRANSMITE A SU DESTINO POR UNA GUIA ONDA OPTICA (7). EL GENERADOR DE SEÑAL DE PRUEBA (5) APLICA UNA PRIMERA SEÑAL DE PRUEBA (FO) AL SUMADOR (1) Y UNA SEGUNDA SEÑAL DE PRUEBA (3FO) AL CIRCUITO DE EVALUACION (4).
