MATLAB: PSD units conversion

psd

I would like to have units of V/RootHz on the Y axis. I can get Volts by removing 10*log10 from code blow, but how do I get /rootHz Code:
fs=2000;
Hs=spectrum.periodogram; % Use default values
psdest = psd(Hs,Signal,'Fs',fs);
semilogx(psdest.Frequencies,10*log10(psdest.Data));
grid on;

Best Answer

You get V^2 by removing 10*log10(), not V.
What do you mean by V/rootHz?
