Fast impedance measurement method using Laplace transformation

Grzegorz Lentka, Jerzy Hoja

Abstract

The paper presents the impedance measurement method using a real-life step pulse as a perturbation signal and Laplace transformation as a tool for analyzing the response of the object under test. The method is addressed to explore different technical object (like anticorrosion coatings, gas sensors, ceramics, dielectrics biological tissues etc.) when the measurement time cannot be long. The presented method is known, but is not very popular because of some limitation. The paper presents the influence of the limitations on the accuracy of the equivalent circuit parameters identification.
