Question 1.
What is a DAC?
Show hintHide hint
Think about how digital recordings translate into sound.
Question 2.
How does resolution affect output levels?
Show hintHide hint
Consider binary systems; each additional bit doubles levels.
3Question 3.
What is the primary function of a Digital-to-Analog Converter?
- To convert analog signals to digital
- To convert digital signals to analog
- To amplify signals
Show hintHide hint
Think about the applications requiring sound or analog signals.
4Question 4.
True or False: A higher resolution in DAC equates to fewer output levels.
- True
- False
Show hintHide hint
Consider how bits represent binary numbers.
Question 5.
If a DAC has a resolution of 4 bits and a reference voltage of 10V, compute the maximum output and the output for a digital input of 5.
Show hintHide hint
Utilize the DAC output formula.
Question 6.
