Question 1.
What is a discrete signal?
Show hintHide hint
Think of examples where data is collected periodically.
Question 2.
Explain the importance of SNR.
Show hintHide hint
Consider how noise affects measurements.
3Question 3.
What does a higher SNR indicate?
- More noise
- Clearer signal
- Less data
Show hintHide hint
Recall the role of SNR in data quality.
4Question 4.
True or False: Discrete signals are collected continuously.
- True
- False
Show hintHide hint
Think about how data is logged in sensors.
Question 5.
If you have collected discrete strain data and the SNR is found to be 5 dB, how would you increase SNR to make your measurements more reliable?
Show hintHide hint
Consider both reducing noise and increasing signal power.
Question 6.
Given a dataset where the signal power fluctuates between 30 and 70 units while the noise power remains constant at 10 units, devise a strategy to ensure a momentary high SNR.
