Question 1.
What is the primary function of a Sigma-Delta DAC?
Show hintHide hint
Think about the main role of a DAC in systems.
Question 2.
What does oversampling achieve in a Sigma-Delta DAC?
Show hintHide hint
Consider how sampling frequency relates to signal quality.
3Question 3.
What is the main advantage of Sigma-Delta DACs over traditional DACs?
- Lower power consumption
- Higher resolution
- Simpler design
Show hintHide hint
Think about what 'resolution' means in the context of audio quality.
4Question 4.
True or False: Noise shaping in Sigma-Delta DACs helps reduce distortion in low-frequency outputs.
- True
- False
Show hintHide hint
Consider how noise relates to frequency response.
Question 5.
Design a simple Sigma-Delta DAC circuit for a low-power audio application. Discuss the benefits it would offer in terms of performance and power efficiency.
Show hintHide hint
Consider the relationship between power, sampling rate, and audio clarity.
Question 6.
Analyze how the performance of a Sigma-Delta DAC would change if it operated at a significantly lower oversampling ratio than typically recommended.
Show hintHide hint
Think about how sampling rates relate to overall signal clarity and distortion.
