3.7. Conclusion

Try these first

1. 1.

   What does an ADC do?

   Hint

   Think about the type of signal each converts.

2. 2.

   What type of output does a DAC provide?

   Hint

   Remember that DAC stands for Digital to Analog Converter.

3. 3.

   What does an ADC do?

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

   Hint

   It's the first step in digital signal processing!

4. 4.

   True or False: DACs are used to convert digital signals into analog signals.

   • True
   • False

   Hint

   Think about how digital files can be heard!

5. 5.

   Design a mixed signal system using ADCs and DACs for a home automation audio control system. Consider how signals will be converted and the required parameters.

   Hint

   Think about each step of signal flow from input to output!

6. 6.

   Critique a proposed mixed signal design where the ADC is located far from the analog input signal source, causing signal degradation.

   Hint

   Reflect on signal integrity issues in real-world implementations.
