8. Signal Processing in Mixed Signal Systems

Try these first

1. 1.

   What does ADC stand for?

   Hint

   Think about the conversion from analog to digital.

2. 2.

   What is the main purpose of filtering?

   Hint

   Remember the different types of filters.

3. 3.

   What is the primary function of an ADC?

   • To convert analog signals to digital
   • To convert digital signals to analog
   • To enhance signal quality

   Hint

   Think about what ADC stands for.

4. 4.

   True or False: Digital filters can only be implemented through hardware.

   • True
   • False

   Hint

   Consider the flexibility of digital techniques.

5. 5.

   Design a simple digital filter for an audio system that minimizes background noise while preserving the audio signal. Explain your choice of filtering technique.

   Hint

   Think about the nature of the noise in your audio signal.

6. 6.

   Analyze the trade-offs between using FIR and IIR filters in a real-time application. What factors might lead you to choose one over the other?

   Hint

   Consider stability, computational burden, and precision when making your choice.
