Try these first

1. 1.

   What is mixed-signal design?

   Hint

   Think about the combination of circuit types.

2. 2.

   Name one application of mixed-signal designs?

   Hint

   Recall the devices that use both types of circuits.

3. 3.

   What does mixed-signal design refer to?

   • Integration of analog circuits only
   • Integration of digital circuits only
   • Integration of analog and digital circuits

   Hint

   Think about the definition of mixed-signal.

4. 4.

   True or False: Digital circuits can introduce noise that affects analog circuits.

   • True
   • False

   Hint

   Consider the interaction between the two circuit types.

5. 5.

   Design a basic mixed-signal system for a smartphone application that processes audio signals. Identify the key components needed and how they will work together.

   Hint

   Consider each functional step in audio processing.

6. 6.

   Discuss potential solutions to minimize noise in a mixed-signal circuit for a wireless communication system.

   Hint

   Think about how physical layout can affect performance.
