Re: Does perfect white noise really exist?


ok there goes my theory in the trash can......I know what you mean, but
no harm in hypothesizing!!!

but even if there were an hypothetical point in space enemating pure
white noise (as defined by completely independent and random samples,
with 0 rxx and a completely flat PSD from -inf to +inf, and thereby
giving Einstein's Special Theory of Relativity a complete toss), the
point is that given the current state and future probable direction of
solid state physics, the very act of measuring "pure white noise" to
determine its "(pure) whiteness" will render it non-white.

Ahem. Let me get this straight. You're saying, even if we break
a few laws of physics and discover there is a white noise source,
then, by the laws of physics, measuring it would make it non-white?

YYYYYeahhh. Rrrrrrigggght.
