Question 1.
What does FFT stand for?
Show hintHide hint
Focus on the speed aspect of Fourier analysis.
Question 2.
What is the purpose of a filter in signal processing?
Show hintHide hint
Remember that filters isolate desired properties.
3Question 3.
What is the purpose of the Fast Fourier Transform?
- To increase signal power
- To visualize time-domain signals
- To compute frequency components efficiently
Show hintHide hint
Think about processing speed in analyses.
4Question 4.
True or False: A filter can only remove frequencies and cannot amplify them.
- True
- False
Show hintHide hint
Consider the function of filters in signal processing.
Question 5.
Given a signal contaminated with multiple noise frequencies, discuss a step-by-step approach to decompose the signal using FFT and filters.
Show hintHide hint
Think about the process of identifying frequencies and then selectively removing them.
Question 6.
A structure exhibits unusual vibrations. Describe how you would use frequency analysis to diagnose potential issues and suggest improvements.
Show hintHide hint
Consider the correlation between peak frequencies and structural integrity.
