Test: Digital Electronics- 3 - Question 11

Identify the incorrect statement

Detailed Solution for Test: Digital Electronics- 3 - Question 11

This statement is incorrect because as the number of steps increases, the resolution of the DAC increases, resulting in finer percentage resolution. Therefore, the statement should be: Percentage resolution increases as the number of steps increases.
