Hz with 10 points per decade. For illustrative purposes, panels (a) and (b) of Figure show the Nyquist plots of the exact, "experimental", and regressed impedances and admittances for 𝑅 ion = 2.00×10 1 Ω and 𝑅 ∞ = 1.00×10 . We observed that 𝑅 ion was responsible for the apparition of one peak around ~1.00×10 0 s in the DCT spectrum, while 𝑅 ∞ led to the appearance of two peaks at ~ 1.00× 10 -1 s and 1.00× 10 0 s. We stress that these observations could not be made with the DRT method.
