2. Sample-and-hold circuits in analog-to digital converters (ADCs) are designed to:
Options
A. sample and hold the output of the binary counter during the conversion process
B. stabilize the comparator's threshold voltage during the conversion process
C. stabilize the input analog signal during the conversion process
D. sample and hold the D/A converter staircase waveform during the conversion process

4. What is the major advantage of the R/2R ladder digital-to-analog (DAC), as compared to a binary-weighted digital-to-analog DAC converter?
Options
A. It only uses two different resistor values.
B. It has fewer parts for the same number of inputs.
C. Its operation is much easier to analyze.
D. The virtual ground is eliminated and the circuit is therefore easier to understand and troubleshoot.

5. What is the resolution of a digital-to-analog converter (DAC)?
Options
A. It is the comparison between the actual output of the converter and its expected output.
B. It is the deviation between the ideal straight-line output and the actual output of the converter.
C. It is the smallest analog output change that can occur as a result of an increment in the digital input.
D. It is its ability to resolve between forward and reverse steps when sequenced over its entire range.
