Answer: Option A
Explanation:
2.
Incorrect codes are a form of output error for a digital-to-analog converter (DAC).
Answer: Option B
Explanation:
3.
If we double the number of bits in our digital representation of a number from 4 to 8 bits, we double the relative accuracy of the conversion from digital to analog.
Answer: Option B
Explanation:
4.
The flash method of analog-to-digital conversion (ADC) uses comparators that compare reference voltages with the analog input voltage.
Answer: Option A
Explanation:
5.
A digital-to-analog converter (DAC) is said to be nonmonotonic if the magnitude of the output voltage increases every time the input code increases.
Answer: Option B
