6. Analog-to-Digital Conversion (ADC)

Try these first

1. 1.

   What does ADC stand for?

   Hint

   Think about the purpose of the device.

2. 2.

   What is the first step in the ADC operation?

   Hint

   It's about measuring the analog signal.

3. 3.

   What is the primary function of an ADC?

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

   Hint

   Think about what happens to the signals.

4. 4.

   True or False: The sampling rate should be less than the Nyquist frequency.

   • True
   • False

   Hint

   Remember the Nyquist Theorem.

5. 5.

   An ADC has a resolution of 12 bits and operates across a voltage range of 0 to 5V. What is the size of the Least Significant Bit (LSB)?

   Hint

   Use the LSB formula we discussed during the session.

6. 6.

   If a SAR ADC operates at a sampling rate of 1 MSPS and has an SNR of 90 dB, what does this imply about the quality of the measurement?

   Hint

   Think about how SNR relates to accuracy.
