Question
Determine the decoded 12-bit code for a resolution of 0.01 V and analog sample voltages +10.234 V.Answer format: XXXXXXXXXXXX, where X is either 1 or 0.
Solution
Para determinar el código de 12 bits decodificado para una resolución de 0.01 V y un voltaje de muestra analógica de +10.234 V, sigue estos pasos:
-
Determinar el número total de niveles posibles: Un código de 12 bits tiene niveles posibles.
-
Calcular el rango total de voltaje: Si la resolución es de 0.01 V, el rango total de voltaje es:
-
Determinar el voltaje mínimo y máximo: Asumiendo que el rango de voltaje es de 0 a 40.96 V (esto puede variar dependiendo del sistema, pero usaremos este rango para este ejemplo).
-
Calcular el valor digital correspondiente al voltaje de muestra:
-
Redondear al entero más cercano:
-
Convertir el valor digital a binario de 12 bits:
Por lo tanto, el código de 12 bits decodificado para un voltaje de muestra de +10.234 V es:
001111111111
