The DR application to a given transfer function \(Z_{xy}\) expressed in the form of (from top to bottom): apparent resistivity \(\rho_{xy}\) and impedance phase \(\arg \left[ {Z_{xy} } \right]\); real and imaginary parts of \(Z_{xy}\); real and imaginary parts of \(C_{xy} = Z_{xy} /i\omega \mu_{0}\); real and imaginary parts of \(Z_{xy}^{n} = Z_{xy} /\sqrt {i\omega \mu_{0} }\)
