Question 1
What is the formula to calculate resolution in an ADC?
- VFS / (N * 2)
- VFS / (2^N - 1)
- VFS * 2^N
💡 Hint: Remember how the bits and voltage range relate!
Question 2
True or False: The sampling rate must exceed the highest signal frequency to avoid aliasing.
- True
- False
💡 Hint: Consider the impact of undersampling a signal!

Challenge Problems
Push your limits with challenges.
Question 1
A 12-bit ADC is used in a prototype sensor for temperature measurement that has a VFS of 10V. Calculate its resolution. How would this affect its performance in capturing subtle temperature changes?
💡 Hint: Apply the formula for resolution carefully!
Question 2
You are tasked with designing an ADC system that requires a minimum sampling rate of 10 kHz to accurately capture an analog signal with a maximum frequency of 3 kHz. What would be the theoretical minimum sampling rate to ensure no aliasing? Explain why exceeding this rate is also beneficial.
💡 Hint: Use the Nyquist theorem to find the formulas and remember the impacts of exceeding minimum rates!
