6 sample questions

Question 1.
What does the resolution of an ADC refer to?
Show hintHide hint
Think about how many different values the output can represent.
Question 2.
Why is the sampling rate important?
Show hintHide hint
Consider what can happen if we sample too slowly.
3Question 3.
What defines the resolution of an ADC?
- Number of sensors
- Number of bits in output
- Input voltage range
Show hintHide hint
Think about how many different values can be represented.
4Question 4.
True or False: Higher SNR is better for signal clarity.
- True
- False
Show hintHide hint
Consider what happens when there is too much noise.
Question 5.
An environmental sensor operates with an ADC that has a sampling rate of 1 kHz. If the signal changes at a frequency of 600 Hz, is this sufficient? Justify your answer.
Show hintHide hint
Apply Nyquist Theorem here for validation.
Question 6.
An engineer is choosing a 12-bit ADC for a sensor that measures 0 to 10V, but accidentally selects an 8-bit ADC. How will this affect measurements?
Show hintHide hint
Consider the effect of fewer steps on signal representation.
