Hello,
Is there a way to have power spectral density results from "pwelch" method or any other method show V/rtHz units on it's y axis. Default units for any method that I found are dB/Hz.
Thanks.

The Signal Processing Toolbox includes a number of functions that convert between units of measure, including:
db2pow
pow2db
db2mag
mag2db
HTH.
