   Hint

   Think about how signals change form.

2. 2.

   Name one key application of signal processing.

   Hint

   Consider where you hear sound.

3. 3.

   What major process does ADC represent in mixed signal systems?

   • Signal filtering
   • Signal conversion
   • Signal modulation

   Hint

   Focus on the aspect of changing signal type.

4. 4.

   • True
   • False

   Hint

   Consider the type of signals that each processing applies to.

5. 5.

   Explain the significance of real-time signal processing in ECG monitoring systems and how it affects patient outcomes.

   Hint

   Consider the importance of promptness in medical situations.

6. 6.

   Design a simple mixed signal system that utilizes both ADC and DAC, explaining the role of each component.

   Hint

   What’s the flow from capturing sound to output?
