We analyse responses in frequency domain and time domain. They significantly differ. Moreover, quadrature and inphase components in frequency domain behave differently in case of airborne IP. We propose resistance calculation which has to be poorly influenced by airborne IP. Also we offered a method for resistivity calculation. We made a comparison of such resistivity and apparent resistivity calculated by the quadrature component. These resistivity data are rather similar. We hope that quadrature component is less affected by AIP. Further researches are required to receive estimates of resistance and capacity for more general case.
