Frequency spectra of the (a) real part $\mathrm{Re}\left({\dot{Z}}_{\mathrm{X}}\right)$ and (b) imaginary part $\mathrm{Im}\left({\dot{Z}}_{\mathrm{X}}\right)$ of the impedance ${\dot{Z}}_{\mathrm{X}}$ comprising the bioimpedance models for $R_{\mathrm{X}}=$0.30 kΩ, $C_{\mathrm{PX}}=$3.22 nF, and coupling capacitance $C_{\mathrm{SX}}=$9.76 nF. DFT data were fitted to Equations (9) and (10) to determine $R_{\mathrm{X}}$, $R_{\mathrm{PX}}$, $C_{\mathrm{PX}},$ and $C_{\mathrm{SX}}$ (dashed lines).
