white noise specta as in a gaussian distn?bunch of pseudorandom uniforms and sum them.
what are you working in?

C++. Not specifically Gaussian as far as I know.So, just a string of random numbers will make for a noise sample?
Then I could FFT that, clip the bandwidth, and inv-FFT it to get the band-limited noise I need?
I just wondered if there was a shortcut to making a spectrum. Could it just be uniform amplitudes with random phase, or will that go 'orribly wrong?

this is tending out of my area.think that you could generate a uniform random vector, mean zero. and then transform such that the autocorrelation is the identity...
/tending to talk out of my arse now, becuase I'm a bit uncertain about how to do what you want to do.

OK ta.At least I know I can start with just random numbers to get a noise signal, and manipulate that as I need to.
