3. In a binary-weighted digital-to-analog converter (DAC), the values of the input resistors are chosen to be proportional to the binary weights of the corresponding input bits.
8. 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.
9. 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.
