Rafer to the Egure below. What, if amyhing, appeans to be wrang with the outout of the D/A converter? Aralog output Binary Select ane: O A. The converter has a nonmanotonic utput error B. It appears that certain irput codes are incarresct; double- check the input coding C. The inpuit sig is probably nosy. D. Ther appears to be some nanlinesarity in the scope dsplay Analog output Binary Figure 12-2 Refer to Figure 12-2 What, if arnything, appears to be wrong with the DNA converter? Select ar: O A. There is a aninesarity eror B. There is an affset error O C. The pawer supply voltage appessrs to be too high o D There is nothing wrong with the crverter. Sigma Delta ADC utlizes Select ane: O A quartized difference betwen two samples O B.delta modulatian O Caone-bit quanization method D all of the aboveExplanation / Answer
1) So much ups and downs for nearly the same voltage level can occur in a sequence if input signal is too much noisy. Therefore C is the right answer.
2) Look at the y axis the signal won't starts from 0, insteas it starts from between 0 and 1, So there is an offset error.
Therefoe B is the correct option.
3) Sigma delta modulations uses all of these, therefore D is the correct option.
