Question
Chapter 4, Problem 4.10QAP
Interpretation Introduction
Interpretation:
The percentage error possessed by an ADC converter for two different voltages should be compared with explanation.
Concept introduction:
As we know that ADC is an analog to digital converter device but it’s not possible to convert the whole data always, there might be some error as well. we know that the percentage error processed by an ADC is given by the formula as below:
