I followed everything until this:
"> Ps of snr is time domation power. "
What does it mean?
Here is a literal translation:
"The power spectral density of the signal of signal to noise ratio is time domation power"
It's gobbledegook.

Yes, of course we can define snr(f), you've already defined it as Ps/Pn
