Abstract

UNA INSTALACION DE GUIA PREFERENTEMENTE UNA INSTALACION DE LINEA TERMINAL (LE) DE UN SISTEMA DE TELECOMUNICACIONES, QUE CONTIENE CIRCUITOS DE EMISION Y DE RECEPCION (S SUB 1, S SUB 2, S SUB N, E), EN LOS QUE ESTAN CONECTADAS LINEAS DE EMISION (EL SUB 1), CONTIENE AL MENOS UN CIRCUITO DE RECEPCION (E SUB 1) CON UNA DISPOSICION DE CIRCUITO (KS) PARA LA COMPENSACION DE DIAFONIAS. UNA DISPOSICION DE CIRCUITO INDIVIDUAL (KS) REALIZA LA COMPENSACION DE LA DIAFONIA (S SUB 1, S SUB 2, S SUB N) EN UNA LINEA DE RECEPCION (EL SUB 1). PARA LA COMPENSACION SE DERIVA DE CADA CIRCUITO DE EMISION (S SUB 1, S SUB 2, S SUB N) UNA SEÑAL DE REFERENCIA (R SUB (1) 1, R SUB (1) 2, R SUB (1) N) Y SE SIMULA MEDIANTE UN FILTRO AUTOADAPTABLE (F SUB 1, F SUB 2, F SUB N) UNA SEÑAL DE COMPENSACION (K SUB 1, K SUB 2, K SUB N). LAS SEÑALES DE COMPENSACION INDIVIDUALES SE MEZCLAN A TRAVES DE LAS ENTRADAS DE SUBSTRACCION DE UN CIRCUITO DE SUBSTRACCION (S) CON LA SEÑAL DE RECEPCION. UNA PARTE DE LA SEÑAL DE SALIDA DEL CIRCUITO DE SUBSTRACCION (S) SE CONDUCE A LAS ENTRADAS DE LAS SEÑALES DE REGULACION (RS SUB 1, RS SUB 2, RS SUB N) DE LOS FILTROS AUTOADAPTABLES (F SUB 1, F SUB 2, F SUB N), LA OTRA PARTE SE PROCESA PARA FORMAR LA SEÑAL DE RECEPCION (DA).
