I have a pressure signal at two locations (r=1 and r=1.3)
. I found the Power spectral density (PSD) and the Root Mean Square (RMS) of the siganl. My question is why at r=1
the PSD is higher than the PSD at r=1.3
while the RMS at r=1
is less than RMS at r=1.3.
I mean is there any relation between PSD and RMS of the signal?
r=1
the PSD is higher than the PSD atr=1.3
[at some frequencies] while the RMS atr=1
is less than RMS atr=1.3.

is higher that the PSD is at `r=1'. $\endgroup$ – robert bristow-johnson Oct 5 '17 at 0:27
