6.2. Principles of ADC Operation

Try these first

1. 1.

   What is the first step in the ADC operation process?

   Hint

   Think about what comes first in converting an analog signal.

2. 2.

   Explain what quantization does.

   Hint

   Consider how we simplify continuous values.

3. 3.

   What is the process of measuring an analog signal at discrete intervals called?

   • Quantization
   • Sampling
   • Encoding

   Hint

   It's the first step in converting to digital.

4. 4.

   True or False: Quantization simplifies the data for easier processing.

   • True
   • False

   Hint

   Consider the role of quantization in ADC.

5. 5.

   An ADC samples a signal with a frequency component of 3 kHz. If it operates at the Nyquist rate, what is the minimum sampling frequency required?

   Hint

   What does the Nyquist theorem say about sampling frequency?

6. 6.

   Explain a scenario in which aliasing might occur and how it affects the performance of an ADC.

   Hint

   Consider what happens if the sampling rate is lower than required.
