Re: Creating noise in the frequency domain?

WN_s -> GN_f
WN_f -> GN_s
GN_s -> GN_f
GN_f -> GN_s

Oh, really that straightforward?
Great, but can you specify what aspect of the complex numbers you are
talking about? Real & imaginary parts or rather magnitude and phase.
From what range do I have to pick values in the frequency domain to
get Gaussian noise in the spatial domain (does it matter)?
And do you have any links or references?

(WN: white noise, GN: gaussian noise, s: spatial domain,
f: frequency domain)

To produce random numbers in the frequency domain should be a fast
way to get gaussian noise in the spatial domain(?).

Jep, if you need to perform frequency domain filtering on the Gaussian
noise, it accelerates the process :-)

Thanks.
