6.1. Continuous Fourier Transform

Try these first

1. 1.

   What does the Fourier Transform do?

   Hint

   Think about what it analyzes in terms of frequencies.

2. 2.

   Name one type of filter used in frequency domain analysis.

   Hint

   It allows certain frequencies to pass through.

3. 3.

   What does the Fourier Transform primarily achieve?

   • Converts time to frequency
   • Measures noise
   • Increases bandwidth

   Hint

   Consider the two domains involved.

4. 4.

   True or False: A low-pass filter allows high frequencies to pass.

   • True
   • False

   Hint

   Think about what happens to unwanted noise.

5. 5.

   Create a signal summary based on given spectral data from a bridge vibration test, identifying potential issues.

   Hint

   Know standard resonant frequencies for bridge types.

6. 6.

   Design an experiment to measure the effect of different filtering techniques on a noisy signal.

   Hint

   Use both low-pass and band-pass filters.
