Abstract

UN RADIOTELEFONO (1) SE SINTONIZA DE MODO QUE EL EQUIPO DE SINTONIZACION (2) SELECCIONA UNA SEÑAL (S1,S2) PARA SINTONIZARLA MEDIANTE EL MICROPROCESADOR (10) Y EL MULTIPLEXOR (13) Y LOS AMPLIFICADORES CONTROLADOS POR LOGICA (11,11'') SE CONTROLAN PARA OBTENER LA SINTONIA DESEADA. LOS VALORES ESTABLECIDOS CORRESPONDIENTES A LA SINTONIZACION SE ALMACENAN EN LA MEMORIA DEL MICROPROCESADOR. CUANDO FUNCIONA EL RADIOES SE AMPLIFICAN DE ACUERDO CON VALORES ESTABLECIDOS. LA SINTONIZACION SE PUEDE REALIZAR SIN ABRIR EL RADIO TELEFONO.
