Show hintHide hint
Consider how signals can be represented differently.
Question 2.
Define the Fourier Amplitude Spectrum.
Show hintHide hint
Think about how each frequency's contribution is represented.
3Question 3.
What does the Fourier Transform accomplish?
- A) Converts time signals into space signals.

Show hintHide hint
Recall the definition of Fourier Transform.
4Question 4.
True or False: The Fourier Amplitude Spectrum shows the contribution of frequencies to a signal.
- True
- False
Show hintHide hint
Think about how it visually represents signal information.
Question 5.
Analyze a given ground motion data set using the Fourier Transform and identify dominant frequencies. How would the results influence structural design?
Show hintHide hint
Look for peaks in the amplitude spectrum to determine dominant frequencies.
Question 6.
Discuss how noise in seismic data can affect the results of a Fourier analysis. What methods can be used to mitigate these effects?
Show hintHide hint
Investigate various filtering techniques used in signal processing.
