Análisis y diseño de osciladores digitales

Abstract

El uso de señales sinusoidales digitales en sectores cada vez más amplios ha motivado una investigación para desarrollar osciladores digitales sinusoidales tema aquí abordado. para ello hemos partido en primer lugar de una revisión critica de los osciladores digitales lineales existentes en la literatura observando que el principal uso de los osciladores recursivos debe centrarse en la obtención de señales sinusoidales de frecuencia mucho menor que la de muestreo. A continuación se ha realizado el diseño de nuevas estructuras en el espacio de estado desarrollando un conjunto de osciladores digitales recursivos lineales que presentan una frecuencia de oscilación muy poco sensible a la cuantización de coeficientes un único coeficiente sujeto a cuantización y muy bajo nivel de ruido de redondeo experimentalmente se ha comprobado la validez de estos resultados. Por último se ha revisado un oscilador no-lineal robusto y propuesto una estructura alternativa. Realizado el estudio de la misma los resultados experimentales posteriores presentan un buen acuerdo con los teóricos.
