5. An experimental analysis of the natural oscillations in a particular structure shows thedominant frequencies of interest appear at below 200 Hz. However, firequency informationalso exists at 350, 450, and 750 Hz. If the signal is sampled at 400 Hz, how will theinformation in the aliased frequencies appear in the sampled data? (Hint: Use the foldingdiagram in the lecture note).
