6.1. Introduction

Try these first

1. 1.

   What does an ADC do?

   Hint

   Think about the signal types.

2. 2.

   Name one application of ADCs.

   Hint

   Consider consumer electronics.

3. 3.

   What is the primary function of an ADC?

   • To amplify analog signals
   • To convert analog signals to digital
   • To store analog signals

   Hint

   Think about what ADC stands for.

4. 4.

   True or False: The Nyquist Theorem states that sampling frequency must be more than twice the highest frequency in the signal.

   • True
   • False

   Hint

   Recall the definition of Nyquist.

5. 5.

   Analyze how the resolution of an ADC can affect the clarity of a digital audio recording.

   Hint

   Consider the quality of sounds you hear when recording different music genres.

6. 6.

   Consider a system where an ADC operates below the Nyquist rate. What issues might arise in signal reconstruction?

   Hint

   Reflect on how human perception might be affected by distorted audio.
