4Question 4.
True or False: A low-pass filter allows high frequencies to pass.
- True
- False
Show hintHide hint
Consider what each type of filter does.
Question 5.
Given a set of sensor readings collected over several trials, demonstrate how you would apply averaging and filtering to enhance the data quality, and explain each step.
Show hintHide hint
Think about how each step contributes to reducing noise.
Question 6.
Explain a scenario in structural health monitoring where both averaging and filtering would be crucial. What potential issues might arise without these methods?
Show hintHide hint
Consider the implications of noisy data in engineering contexts.
