Time-domain measurement of spectra of stochastic electromagnetic fields
Time-domain EM spectrum and electromagnetic interference (EMI) measurement systems sample the broad-band EMI signal with GHz sampling rates and compute the EMI spectrum by digital signal processing, e.g. by the fast Fourier transform (FFT). This yields a considerable reduction of the measurement time by up to five orders of magnitude.
