8.4. Real-World Case Studies

Try these first

1. 1.

   What does ECG stand for?

   Hint

   Think about heart monitoring.

2. 2.

   Name one DSP technique used in smart audio devices.

   Hint

   Consider how these devices process sounds.

3. 3.

   What is the primary purpose of an ADC in ECG devices?

   • To filter signals
   • To digitize analog signals
   • To amplify signals

   Hint

   Think about what happens before signal processing.

4. 4.

   True or False: DSP techniques can only be applied in audio systems.

   • True
   • False

   Hint

   Consider the variety of systems that use signal processing.

5. 5.

   Design an algorithm to improve the accuracy of heart rate detection in wearable ECG devices considering noise and interference.

   Hint

   Consider methods to reduce baseline noise.

6. 6.

   Evaluate the implications of switching from analog to digital signal processing in industrial applications. Discuss at least three key benefits.

   Hint

   Think about the advantages of reprogrammable systems.
