54 Ya.M. Blanter, M. Bu( ttiker / Physics Reports 336 (2000) 1}166 measured and correlated with the intensity #uctuation dI (t#), where is a short time smaller than the response time of the detector. The coincidence rate C is thus C "(1/2) ddIK (t)dIK (t#)#dIK (t#)dIK (t) . (104) The coincidence rate is related to the frequency-dependent noise power spectrum by C "(1/) d d eS () . (105) In Section 3, we discuss the frequency dependence of the noise power spectrum in more detail. Typically, its lowest characteristic frequencies are given by RC-times. In principle, such a measurement should, therefore, be able to give information on the frequency dependence of the noise power spectrum. In the experiment of Oliver et al. the resolution time is probably long compared to such intrinsic time scales, and thus the experiment is e!ectively determined by the white-noise limit of the power spectrum. Let us now brie#y consider a Y-shaped conductor [21] and discuss its correlations in the white-noise limit. We assume that the same voltage < is applied between the terminals 1 and 2, and 1 and 3: " #e
