Abstract

SE PRESENTAN UN METODO Y UN APARATO DE ANALISIS POR SINTESIS GENERALIZADO. SE GENERAN UNA PLURALIDAD DE SEÑALES ORIGINALES ENSAYO EN BASE A UNA SEÑAL ORIGINAL PARA LA CODIFICACION. LAS SEÑALES ORIGINALES DE ENSAYO SE CONTROLAN DE MODO QUE SEAN PERCEPTIBLEMENTE SIMILARES A LA SEÑAL ORIGINAL. LAS SEÑALES ORIGINALES DE ENSAYO SE CODIFICAN PARA PRODUCIR UNO O MAS PARAMETROS REPRESENTATIVOS DE LAS MISMAS. LOS VALORES ESTIMADOS DE LAS SEÑALES ORIGINALES DE ENSAYO SE SINTETIZAN A PARTIR DE ESTOS PARAMETROS. SE DETERMINAN LOS ERRORES ENTRE LAS SEÑALES ORIGINALES DE ENSAYO Y LOS VALORES SINTETIZADOS. SE DETERMINA UNA REPRESENTACION CODIFICADA DE LA SEÑAL ORIGINAL QUE MODO QUE COMPRENDA PARAMETROS DE LA SEÑAL ORIGINAL DE ENSAYO CON UN ERROR ASOCIADO QUE SATISFAGA A UN PROCESO DE EVALUACION DE ERRORES. LAS SEÑALES ORIGINALES DE ENSAYO SE PUEDEN GENERAR APLICANDO TERGIVERSACIONES TEMPORALES O DESPLAZAMIENTOS TEMPORALES EN LA SEÑAL ORIGINAL. LA CODIFICACION DE UNA SEÑAL ORIGINAL DE ENSAYO SE PUEDE LLEVAR A CABO MEDIANTE UNA CODIFICACION DE ANALISIS POR SINTESIS CONVENCIONAL TAL COMO UNA CODIFICACION DE PREDICCION LINEAL EXCITADA POR CODIGOS (CELP). SE PUEDE UTILIZAR UN PROCESO DE ERRORES AL CUADRADO MINIMO A MODO DE CRITERIO DE ERRORES.
