Discrete version of Wiener-Khinchin theorem for Chebyshev’s spectrum of electrochemical noise

The reassigned pseudo Wigner–Ville transform in electrochemical noise analysis

“…27 Many procedures to remove drift have been presented so far, including linear trend removal, 28 polynomial fitting, digital filtering, 29 wavelet transform, empirical mode decomposition, 30 or employment of a discrete version of the Wiener-Khinchin theorem. 31 Nevertheless, selecting the ideal method to deal with the baseline problem and to distinguish the drift from the useful information remains open.…”
