Abstract
Un dispositivo a base de microprocesador (1) para generar una representacion de la distorsion armonica total en una forma de onda de corriente alterna (W) deriva de muestras digitales de la forma de onda de una señal fundamental (F) que representa el valor del componente de frecuencia fundamental de cada muestra. Entonces se genera una señal de armonicos como la diferencia entre el valor de muestra y el componente fundamental de la muestra. Una señal de salida que representa la distorsion armonica total es entonces generada como la relacion del valor rms de la señal de armonicos al valor rms de la señal fundamental convertida en un porcentaje.
