Question

An 8-bit ADC has a digital resolution of %.

Answer 1

Answer:

0.39 %

Explanation:

We have given 8 bit ADC and we have to find the resolution of the ADC

The resolution of the ADC is given by $resolution=\frac{1}{2^n-1}$ where n is the number of bit

Here in question we have given 8 bit ADC so n = 8

So resolution is given by $resolution=\frac{1}{2^n-1}=\frac{1}{2^8-1}=\frac{1}{255}=0.003921$ =0.39%
