Method Using Square-Pulse Excitation for High-Impedance Spectroscopy of Anticorrosion Coatings
− The paper presents a new method of impedance measurement for impedance spectroscopy. The method is based on square pulse excitation and digital signal processing of sampled current and voltage response. The main innovation in the proposed method is sampling moments optimisation adequate to the object under test. The method was tested by Matlab simulations and results are not worse than in previous version of the method while assuring smaller number of samples (lower processing efforts) and wider impedance spectrum frequency range.
