Abstract
LA PRESENTE INVENCION UTILIZA UNA TABLA DE CONVERSION UNA PARTE DE LA CUAL ESTA DUPLICADA CON EL FIN DE CONVERTIR DIRECTAMENTE DATOS DE ENTRADA DE M-BIT EN UN CODIGO N-BIT SIN UTILIZAR UN BIT DE MARGEN. ESTA TABLA DE CONVERSION COMPRENDE UNA PRIMERA Y SEGUNDA SUB-TABLAS QUE INCLUYE CADA UNA PLURALIDAD DE GRUPOS DE CODIGOS, Y ESTOS GRUPOS DE CODIGO CONTIENEN DIFERENTES CODIGOS PARA LOS MISMOS DATOS DE ENTRADA. EN LA SEGUNDA SUB-TABLA, SE DUPLICA UNA PARTE DE LA PRIMERA SUB-TABLA QUE OBTIENE MEDIANTE LA ASIGNACION DE DIFERENTES CODIGOS A LOS DATOS QUE VARIA DESDE LOS PRIMEROS DATOS DE ENTRADA A LOS SEGUNDOS DATOS DE ENTRADAS DE LA SUB-TABLA. EL CONJUNTO DE LOS CODIGOS DE LA PARTE DUPLICADA DE LA TABLA DE CONVERSION ES ASI CONSTITUIDA PARA TOMAR UNA VARIACION SUMA DIGITAL DE SIGNOS OPUESTOS, Y LOS CODIGOS SON POSTERIORMENTE ASIGNADOS A LOS DATOS DE ENTRADA DESDE EL CODIGO QUE TIENE EL VALOR ABSOLUTO SUPERIOR DE LA VARIACION SUMA DIGITAL. DE ESTA FORMA, LA PRESENTE INVENCION PUEDE SUPRIMIR DE FORMA APROPIADA COMPONENTES DE BAJA FRECUENCIA DE SEÑALES DE MODULACION.
