Dynamic normalization of the Barkhausen noise signal
Original language description
The aim of this research is to propose a normalization principle for the Barkhausen noise response eliminating a dynamic contribution to the basic signal. To achieve this, it is suggested to reduce the rms profile (envelope) of the Barkhausen noise by the square root of the field rate of change. Validity of the suggested normalization principle has been proved for variousiron-based steels. At low magnetizing frequencies, the proposed normalization fully compensates the envelope differences giving a stable quasi-static peak near coercive field. The shape of these stabilized peaks demonstrates a strong resemblance to the differential permeability curves.
