in the form of Power Spectral Density (PSD).
​

Answer 1

Answer:

3 Points to be Remembered

• The excitation is applied in the form of Power Spectral Density (PSD).

• The PSD is a table of spectral values vs. frequency that captures the frequency content.

•The PSD captures the frequency and mean square amplitude content of the load's time history.
