I don't understand what you second claim is. Are you saying that the rms
value in the time domain is equal to the rms value in the frequency
domain, if so you have missed something, cos this aint so. I have
consistently said, the rms/sd value of the *width* in *time* and the
rms/sd of the *width* in *frequency*. It would seem that you may be
referring to the *height*, i.e. its voltage/amplitude value, which is
indeed specified to be the same in both domains.
