3.4.2. Common Components

Try these first

1. 1.

   What does an ADC stand for?

   Hint

   Think about what it converts.

2. 2.

   What is one application of a DAC?

   Hint

   Consider how we hear sound.

3. 3.

   What does an ADC do?

   • Converts digital to analog
   • Converts analog to digital
   • Amplifies signals

   Hint

   Focus on the first part of the term ADC.

4. 4.

   True or False: A DAC is only used in audio applications.

   • True
   • False

   Hint

   Think of other areas where digital signals are converted to analog.

5. 5.

   Design a simple signal flow for a mixed signal system using ADCs and DACs for an audio application. Explain why you chose each component.

   Hint

   Draw out the flow for clarity.

6. 6.

   Evaluate the impact of increasing the resolution of an ADC on its power consumption and performance. Discuss your findings.

   Hint

   Consider trade-offs between quality and energy efficiency.
