Abstract: The Josephson junction noise detector measures the skewness of non-Gaussiannoise via the asymmetry of the rate of escape from the zero-voltage state uponreversal of the bias current. The feedback of this detector on the noisegenerating device is investigated in detail. Concise predictions are made for asecond Josephson junction as noise generating device. The strong nonlinearityof this component implies particularly strong feedback effects, including achange of sign of the rate asymmetry as the applied voltage approaches twicethe superconducting gap.
