Abstract

SISTEMA PARA EL MANTENIMIENTO DEL NIVEL DC EN RECEPTORES OPTICOS EN RECEPCION A RAFAGAS QUE CONSISTE EN LA REALIZACION DE UN PSEUDO-ACOPLAMIENTO DC, QUE CONSISTE EN HACER UN ACOPLAMIENTO AC CON UN CONDENSADOR MUY GRANDE, LO SUFICIENTE PARA QUE EL TIEMPO DE CARGA SEA MUCHO MAYOR QUE LA DURACION DE VARIAS RAFAGAS, Y EL USO DE UN CIRCUITO NUEVO DE CONTROL QUE PERMITE MANTENER UN DETERMINADO NIVEL DC.SYSTEM FOR THE MAINTENANCE OF THE DC LEVEL IN OPTICAL RECEPTORS IN RECEPTION TO GUSTS THAT CONSISTS IN THE REALIZATION OF A PSEUDO-COUPLING DC, WHICH CONSISTS OF MAKING AN AC COUPLING WITH A VERY LARGE CAPACITOR, WHICH IS ENOUGH FOR A LONGER CHARGE TIME THAT THE DURATION OF SEVERAL GUSTS, AND THE USE OF A NEW CONTROL CIRCUIT THAT ALLOWS TO MAINTAIN A CERTAIN DC LEVEL.
