Abstract

LA INVENCION DESCRIBE UN RECEPTOR DE RADIO CON APARATO DE SELECCION DE FRECUENCIA DIGITAL. EL ALMA DE LA INVENCION ES EL SIMPLIFICAR LA SELECCION DE FRECUENCIA PARA TRANSMISORES EN SEPARACIONES DE LA MISMA FRECUENCIA (9 KHZ), Y EL REDUCIR LOS ERRORES DE SELECCION DE FRECUENCIA. DESPUES DE LA ENTRADA DE LA FRECUENCIA SELECCIONADA HASTA EL PENULTIMO DIGITO, EL ULTIMO DIGITO SE CALCULA POR UN PROCESADOR (7) EN BASE A LA SEPARACION DE LA FRECUENCIA CONOCIDA (9 KHZ). LA INVENCION ES PARTICULARMENTE APLICABLE A RECEPTORES DE RADIO CON SELECCION DE FRECUENCIA DIGITAL PARA LA RECEPCION DE OM Y OL.
