Abstract
Un método y aparato para generar señales de corrección para utlizar en la formación de señales análogos de baja distorción. Una representación digital de una forma de onda análoga deseada es codificada en una señal de datos digital, la cual es sacada a la memoria. Una señal de corrección digital es codificada, teniendo una fase opuesta y una amplitud aumentada de la distorsión de señal, la cual es determinada, ocurrirá cuando la señal de datos digital sea repetitivamente leída fuera de la memoria y codificada. Esta señal de corrección digital es sacada a la memoria. Las señales de datos digitales y de corrección son repetitivamente y sincronizadamente leídas fuera de la memoria en un decodificador. El decodificador convierte ambas señales digitales en señales análogas, de modo tal que la señal de corrección análoga pueda superponerse sobre la distorsión en la señal de dato análoga, dando como resultado una señal análoga de baja distorsión.
