In this paper we analyse the statistical physical noise behavior of the broad-band time-domain electromagnetic interference measurement system. The digital signal processing of EMI measurements allows to emulate in real-time the various modes of conventional analogous equipment, e.g. peak-, average-, RMS- and quasi-peak- detector mode. Because the signals encountered in typical EMI measurement scenarios am of stochastic nature, a statistical physical noise analysis of the detector modes is necessary. The signal processing of white Gaussian noise and the measurement results obtained from the investigation of a DC/DC-converter obtained with the time-domain electromagnetic interference (TDEMI) measurement system are discussed.     «
