DIFFERENTIAL IMPEDANCE ANALYSIS - AN INSIGHT INTO THE EXPERIMENTAL-DATA

A new method far analysis of the experimental data of the impedance sp ectroscopy is presented. The method is based on the assumption of a lo cal operating model. Using the derivatives of the impedance with respe ct to frequency, the model parameters and their effective time-constan ts are calculated for each frequency. The analytical equations are use d as a moving estimator over the entire frequency range. Important pro perties of the studied system can be derived.
