Abstract

Se describe un dispositivo de determinación de tono que determina la tonalidad de una señal de entrada utilizando las correlaciones entre los componentes de frecuencia de un cuadro actual con los componentes de frecuencia del cuadro anterior, de manera que el dispositivo de determinación de tono es capaz de disminuir la complejidad del cálculo. En el dispositivo, una unidad de acoplamiento de vector (104) acopla algunos de los coeficientes SDFT del cuadro anterior con algunos de los coeficientes SDFT de muestreo descendente del cuadro anterior para generar nuevos coeficientes SDFT, y también acopla algunos de los coeficientes SDFT del cuadro actual con algunos de los coeficientes SDFT de muestreo descendente del cuadro actual para generar los nuevos coeficientes SDFT. Una unidad de análisis de correlación (105) busca las correlaciones para los coeficientes SDFT entre los cuadros y también busca la potencia del cuadro actual para cada banda específica. Una unidad de determinación de banda (106) determina la banda con la potencia más grande y da salida a la información de ubicación para la banda determinada como la información de cambio, y una unidad de determinación de tono (107) determina la tonalidad de la señal de entrada de acuerdo con los valores de las correlaciones que son ingresados desde la unidad de análisis de correlación (105).
