Abstract

CIRCUITO PARA EL PULSADO DE LINEAS DE TRANSMISION DE DATOS.EL CIRCUITO (K) CONECTA EL TERMINAL (T) A LA LINEA (L) QUE LO ENLAZA CON LA CENTRAL TELEFONICA. EN EL UN ELEMENTO ELECTRONICO DE CONMUTACION (T1) ACTUA COMO CONTACTO EMISOR PARA EL PULSADO DE LA CORRIENTE DE LA LINEA (TL). DICHO CIRCUITO CONTIENE ADEMAS UN FILTRO (F) CUYA CARACTERISTICA ESTA IMPRESA POR EL EFECTO DE LA TENSION DE REFERENCIA DE LA TRAYECTORIA DE LA CORRIENTE (IL) XTREGULADA POR EL CIRCUITO.
