suppose I have 5 frequencies with g^2/Hz values

1Hz, 2Hz, 3Hz, 4Hz, 5Hz and its g^2/Hz values (Here By central frequency you mean 3 Hz here I assume (Please correct me if central frequency is some concept here) . Now in harmonic if I give 3 Hz as frequency and a load/force for it, wouldnt it apply sinusoidal load by default at 3 Hz? whereas in PSD data, the data might not be equivalent to a sinusoidal type force.
