dc.description.abstractDetermination of the weighting function of the Preisach hysteresis model depends strongly on the quality of experimental data. The paper focuses on errors in the input excitation current. The analysis of experimental data and their processing were identified the main source of errors: RF noise, quantization noise at signal synthesis, power net interference and short-term faults of used power supply. Their reduction is possible by insertion of the filter in between the power source and measured sample. The filter was designed with respect to main frequencies of both the useful and disturbing signal. Its simulations are validated with measurements and the improvement of measured waveforms in the time domain is demonstrated.en
