Im trying to calculate the measurement error when using a 4bit resolution input module with a 0-5V range to measure a 5V signal.
What is the measurement error if the voltage at the input channel is 5V?
here is my calculation
5V / 16 (from 4 bits) = 0.3125 voltage resolution
with 0.3125 voltage resolution, the maximum voltage that the input module can represent is .3125 * 15 = 4.6875V.
Therefore the error % is
[(5-4.6875)/5] * 100 = 6.25 %
Is my calculation correct? Also, what do you call the 4 bit digital value that represent the analog input signal voltage?
