What does ADC stand for?
Show hintHide hint
Think about the purpose of the device.
Question 2.
What is the first step in the ADC operation?
Show hintHide hint
It's about measuring the analog signal.
3Question 3.
What is the primary function of an ADC?
- To amplify analog signals
- To convert analog signals to digital signals
- To store digital data
Show hintHide hint
Think about what happens to the signals.
4Question 4.
True or False: The sampling rate should be less than the Nyquist frequency.
- True
- False
Show hintHide hint
Remember the Nyquist Theorem.
Question 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)?
Show hintHide hint
Use the LSB formula we discussed during the session.
Question 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?
Show hintHide hint
Think about how SNR relates to accuracy.
