Abstract

Un método para medir un voltaje desconocido (VIN) usando una red divisora de voltaje, en tal forma que las incertidumbres en los valores de las resistencias, no afectan la medición. El voltaje desconocido se divide en tres voltajes fraccionales y se computa el voltaje desconocido, en la base de los voltajes fraccionales. El voltaje desconocido se divide con un divisor de voltaje que comprende primera, segunda y tercera resistencias, y se mide un primer voltaje (V01) a través de la primera resistencia, se mide un segundo voltaje (V02) a través de la segunda resistencia y se mide un tercer voltaje (V03) a través de la tercera resistencia. Se computa el voltaje desconocido VIN de acuerdo con las ecuaciones descritas en la especificación.
