Abstract

Trata de un método para la codificacion de una senal analogica que tiene una amplitud con una densidad de probabilidad no uniforme; el método comprende:la cuantificacion de la senal segun caiga dentro de una de multiples rangos de niveles desena l y la codificacion de la senal cuantificada por medio de laasignacion de palabras de codigo, cada una tiene multiples dígitos de valor binario, a los niveles de cuantificacion para generar un mensaje codificadoen binario; en donde laspalabras d e codigo son asignadas a los niveles de cuantificacion de acuerdo con la probabilidad de ocurrencia de los nivelesde cuantificacion y el numero de bits que tienen un primer valor (1) en la palabra de codigo tal que los niveles decuantificac ion de mayorprobabilidad de ocurrencia son asignados a palabras de codigo con menos bits que tienen un primer valor (1) que aquellas asignadas a los niveles decuatificacion de menor probabilidad de ocurrencia. La codificacion incluyela gener acion del mensaje codificado en binario tal que el numero de bits enel mensaje codificado es hecho mínimo.
