## Homework Statement

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

## Homework Equations

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),

maximum error

= Q error + C error

=5mV + 2.55mV

= 7.55mV

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.
