An 8 bit ADC has a full scale input of 2.55V. If other cumulative errors are 2.55mV, determine the maximum error.
Options are: 10mV, 2.55mV, 12.55mV, 7.45mV
I believe this is a conceptual question. The only equation I can come up with is that the quantization error in an ADC is at max, half of LSB.
The Attempt at a Solution
Assuming cumulative errors as mentioned in the question does not include quantization error (LSB/2),
= Q error + C error
=5mV + 2.55mV
If cumulative errors include Q error, then max error = 2.55mV as the other errors that can creep into an ADC are non-linearity and aperture errors, both of which more data to calculate.
