Abstract

METODO PARA DESMODULAR UNA SEÑAL DE DATOS CODIFICADA EN CUATRO FASES Y DOS NIVELES. LA SEÑAL, CODIFICADA EN CUATRO FASES, SE APLICA DIRECTAMENTE A UN TERMINAL (5) DE ENTRADA, Y A TRAVES DE UN DISPOSITIVO DE RETARDO (8) A UN AMPLIFICADOR DIFERENCIAL (34), CUYA OTRA ENTRADA DISPONE DE LA SEÑAL SIN RETARDAR. LA SALIDA ES APLICADA A UN CONMUTADOR (35) MONOPOLAR. UN DISPOSITIVO (13) DE ESTABLECIMIENTO DE SINCRONISMO CONTROLA EL CONMUTADOR (35) DE FORMA QUE LA SEÑAL PASA A UN DISPOSITIVO COMBINADOR (16) DIRECTAMENTE O A TRAVES DE UN ELEMENTO (17) DE RETARDO. SE OBTIENE ASI, EN LA SALIDA (18), LA INFORMACION DECODIFICADA E INTERCALADA. EXISTEN OTRAS ORDENACIONES DE COMPONENTES PARA CUMPLIR CON LA MISION DEL METODO.
