Abstract
EN LA REPRODUCCION DE UNA SEÑAL DE AUDIO, EN PARTICULAR, DE UNA SEÑAL DE AUDIO DIGITAL, SE PRESENTAN DEFECTOS AISLADAMENTE O DE FORMA CONTINUA, LOS CUALES YA NO SE PUEDEN CORREGIR CON EL CORRESPONDIENTE SISTEMA CORRECTOR DE DATOS. EN TAL CASO SE EFECTUA ENTONCES UNA INTERPOLACION QUE EFECTUA UNA ESTIMACION DE LA POSIBLE SEÑAL Y LA CUAL NO SE PUEDE PERCIBIR HASTA UN CIERTO GRADO POR EL OIDO. UNA INTERPOLACION DE ESTA CLASE SE REALIZA, POR EJEMPLO, EN LOS CIRCUITOS SONY-IC CXD1167Q O PHILIPS SAA7220. UN INCONVENIENTE DE ESTOS DISPOSITIVOS ES EL HECHO DE QUE LAS INTERPOLACIONES SE PERCIBEN HASTA UN CIERTO GRADO POR EL USUARIO. LA TAREA DE LA INVENCION ES HACER INAUDIBLES LAS INTERPOLACIONES EN LA SEÑAL DE AUDIO. DE ACUERDO CON LA INVENCION SE PROPONE UN PROCESO Y UN CIRCUITO PARA LA REPRODUCCION DE UNA SEÑAL DE AUDIO, QUE EN FUNCION DE LA TASA DE INTERPOLACIONES O ERRORES LIMITEN Y/O REDUZCAN LAS PROPORCIONES DE FRECUENCIA DE LA SEÑAL DE AUDIO EN SU AMPLITUD. DE APLICACION EN APARATOS DIGITALES DE RECEPCION, GRABACION O REPRODUCCION.
