IMPLEMENTATION OF ACCELERATED IMPEDANCE SPECTRUM MEASUREMENT METHOD

Marek Niedostatkiewicz, Romuald Zielonko
  • Abstract:
    The paper presents the implementation of accelerated impedance spectrum measurement method, oriented for technical objects modelled by a linear equivalent circuit, e.g anticorrosion coatings. The method is based on multisine signal stimulation of an object and response analysis by triangle window filter-banks. It has several advantages, as compared with conventional point-by-point spectrum measurement. The method was implemented in an experimental measurement system, based on a DAQ card. The achieved experimental results are discussed and compared with simulation results, in terms of measurement time reduction and accuracy.
