Answer 1

A 4−bit DAC produces 22 mV output for a digital input of 1011.
What is the resolution for this DAC? Find out Vout for 0101.


What is the resolution for this DAC?
Resolution of DAC is the number of possible output levels the DAC is designed to reproduce.
24=16

Find out Vout for 0101.
Input 1011 equal to state level 11, what is the mean, that quantization level of DAC is
22 mV/11 = 2 mV

Input 0101 equal to state level 5, and output of DAC must be:
Vout = 2 mV * 5 = 10 mV
