# Electric noise, Wikipedia [http://en.wikipedia.org/wiki/Electronic_noise]
#: Meget kort omkring de enkelte typer af elektrisk støj.
## Shot noise, Wikipedia [http://en.wikipedia.org/wiki/Shot_noise], [http://en.wikipedia.org/wiki/Photon_noise]
##: Shot noise kommer af at vi har diskrete ladningsbærere (elektroner eller fotoner), der er underlagt poisson statistik. 
# Recent Advances in Studies of Current Noise [http://arxiv.org/abs/cond-mat/0511478]
#: This is a brief review of recent activities in the field of current noise intended for newcomers. We first briefly discuss main properties of shot noise in nanostructures, and then turn to recent developments, concentrating on issues related to experimental progress: non-symmetrized cumulants and quantum noise; counting statistics; super-Poissonian noise; current noise and interferometry.

#: Eksempler på processer der er Poisson fordelt.
