The profound impact of negative power law noise on the estimation of causal behavior
Victor S. Reinhardt · 2009
This paper demonstrates that highly correlated negative power law (neg-p) noise - noise with a PSD prop |f|pwhen pc, where taucis the correlation time of the noise process involved. Finally, it is shown that this is unachievable for neg-p noise, because tauc= infin for such noise (unless system highpass filtering makes taucfinite for the system filtered noise variable).
