Abstract

Se propone un método y aparato para determinar una función de ponderación para cuantificar un coeficiente de codificación predictiva lineal (LPC) y que tiene una baja complejidad. El aparato de determinación de función de ponderación puede convertir un coeficiente LPC de un subcuadro intermedio de una señal de entrada en uno de un coeficiente de frecuencia espectral de imitación (ISF) y un coeficiente de frecuencia espectral de línea (LSF), y puede determinar una función de ponderación asociada con una importancia del coeficiente ISF o el coeficiente LSF con base en el coeficiente ISF o coeficiente LSF convertido.
