Download Transmisión y Modulación (Spanish Edition) by Sergio Martin PDF

By Sergio Martin

Las telecomunicaciones son posibles siempre y cuando sea posible salvar grandes distancias. Aunque medios como el antiguo telégrafo lograban esto gracia al uso de cables de cobre, y en l. a. actualidad mucha de las comunicaciones a grandes distancias y alta velocidad se logran mediante fibra óptica, aun quedan obstáculos que solo son posibles mediante el uso de transmisiones inalámbricas, que son las que requieren de un acondicionamiento especial de l. a. información llamado modulación. Siempre que se hace uso de l. a. modulación, es porque el medio de transmisión presenta características que hacen que los angeles señal de información en su forma unique no pueda transmitirse, o de hacerlo esta se degrade a una distancia muy corta de su punto de origen. Así por ejemplo l. a. voz humana tiene un alcance limitado al viajar por el aire, pero los sonidos emitidos por los elefantes a baja frecuencia pueden recorrer kilómetros, y los sonidos de alta frecuencia de los delfines aun más. Significa, que si los angeles información de nuestra voz pudiese "adecuarse" o "modularse" en otro rango de frecuencias, las limitaciones impuestas por el aire, o aún, el vació podrían eliminarse, o tendrían muy poca repercusión.
