چکیده
This work analyzes the advantages of broad-band time-domain the electrical measurement applied to electromagnetic interference (EMI) problems. The digital signal processing of EMI measurements allows to emulate in real-time the various modes of conventional analogous equipment. Since time-domain techniques allow processing the amplitude and phasing information of the whole signal spectrum in parallel, the measurement time may be reduced by at least one order of magnitude. On details the signal processing algorithms and the measurement results obtained with the time-domain electromagnetic interference system. Key-Words: Conducted EMI, Fast-Fourier Transform, Analog Digital Converter, Modeling, Signal Processing, EMC.
