Editing Pink noise (section)

=== Distribution of point values ===
Consider pink noise of any dimension that is produced by generating a Gaussian white noise signal with mean <math>\mu</math> and sd <math>\sigma</math>, then multiplying its spectrum with a filter (equivalent to spatially filtering it with a filter <math>\boldsymbol{a}</math>). Then the point values of the pink noise signal will also be normally distributed, with mean <math>\mu</math> and sd <math>\lVert \boldsymbol{a} \rVert \sigma</math>.<ref name="Das-thesis">{{cite thesis |last=Das |first=Abhranil |date=2022 |title=Camouflage detection & signal discrimination: theory, methods & experiments (corrected) |type=PhD |publisher=The University of Texas at Austin |url=http://dx.doi.org/10.13140/RG.2.2.10585.80487 |doi=10.13140/RG.2.2.10585.80487}}</ref>
