Abstract

SE TRATA DE UN ESPACIO DE TRANSMISION (1) EN UN MEDIO EN EL QUE PASAN UNA SERIE DE SEÑALES CON IMPULSO (4) Y PAUSA (5) CAPTADOS POR UN RECEPTOR (3). LA INVENCION HA PREVISTO QUE PARA LA MODULACION DE LOS IMPULSOS(4) HAYA AL MENOS DOS FRECUENCIAS (F1,F2...) Y QUE EN EL RECEPTOR HAYA UN SINTONIZADOR (6,7) PARA CADA UNA DE LAS FRECUENCIAS (F1, F2...). A TAL EFECTO LOS SINTONIZADORES ESTAN DISPUESTOS EN CONEXION-U.N.D.
