Abstract
APARATO PARA CONVERTIR UNA SEÑAL MULTIPLEX DE DIVISION DE FRECUENCIA (FDM) EN SEÑAL MULTIPLEX DE DIVISION EN EL TIEMPO (TDM). EL APARATO INCLUYE UN OSCILADOR CONTROLADO POR TENSION (21) CUYA SALIDA ES UNA ESCALERA DE FRECUENCIAS DE REFERENCIA MEZCLADAS POR UN MEZCLADOR (20) CON UNA SEÑAL RECIBIDA (FDM) CADA FRECUENCIA RECIBIDA SE ENVIA EN UNA FRECUENCIA INTERMEDIA COMUN POR UN FILTRO PASABANDA (22), FORMANDO ASI UNA SEÑAL (FDM) TRAS PASAR A TRAVES DE UN DESMODULADOR (23) Y UN FILTRO PASABAJAS (24). LA CONVERSION PUEDE TENER LUGAR EN EL CAMPO OPTICO MEZCLANDO FRECUENCIAS DE REFERENCIA OPTICAS CON UNA SEÑAL (FDM) OPTICA EN, POR EJEMPLO, UN RECEPTOR OPTICO HETERODINO COHERENTE.
