Abstract

In this paper, the magnetic leakage flux, eddy current, and Barkhausen noise method were used to detect minor changes of material properties. Selected digital signal processing algorithms were applied in order to enhance the obtained signals and extract parameters suitable for quantitative evaluation. A comparison between results obtained from all methods was conducted.
