Abstract

Un procesador de señal (100; 1010; 1020) para proporcionar una versión procesada (112; s1'(n); Q1'(n)) de una señal de entrada en dependencia de la señal de entrada (110; s1(n); q1(n)), en el que la señal de entrada es una señal de audio o una señal de vídeo, comprendiendo el procesador de señal: un formador de ventana (120; 1014; 1024), configurado para hacer en ventanas una porción de la señal de entrada, o de una versión pre-procesada de la misma, dependiente de una ventana de procesamiento de señal (1600) descrita por valores de ventana de procesamiento de señal (w(n); w1(n)) para una pluralidad de valores índice de valor de ventana (n) con el fin de obtener la versión procesada de la señal de entrada; y un proveedor de ventana (130; 603, 604, 605, 606; 609, 605, 606) para proporcionar los valores de ventana de procesamiento de señal para la pluralidad de valores índice de valor de ventana dependientes de uno o más parámetros de forma de ventana (132; a1); en el que el proveedor de ventana se configura para evaluar una función seno para una pluralidad de valores de argumento (c'(n)) asociados con los valores índice de valor de ventana (n), para obtener los valores de ventana de procesamiento de señal (w(n)); en el que el proveedor de ventana se configura para calcular una suma ponderada de un término lineal (c(n)), que es linealmente dependiente de los valores índice de valor de ventana (n), y valores de función de una o más funciones de conformación, cuyas una o más funciones de conformación mapean los valores índice de valor de ventana (n) sobre los valores de función correspondientes y cuyas una o más funciones de conformación son simétricas por puntos con respecto a un centro de una pendiente de ventana (1630), para obtener los valores de argumento; en el que las características de la ventana definidas por los valores de ventana de procesamiento de señal se ajustan modificando la ponderación de la una o más funciones de conformación dependientes del uno o más parámetros de forma de ventana, de manera que pueden obtenerse ventanas de diferentes características.
