Investigation on accelerated impedance spectrum measurement method with multisine signal stimulation
Abstract
The paper presents an investigation on the accelerated impedance spectrum measurement method, oriented at parameter identification of 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 filterbanks.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 achievedexperimental results are discussed and compared with simulation results, in terms of measurement time reduction and accuracy.
