Magnetic Barkhausen Noise Spectral Emission of Grain Oriented Steel Under Ultra Low Frequency Magnetization
The Barkhausen noise spectrograms for ultra low frequency triangular excitation signal are presented. The current source is used for sample excitation to ensure the exact waveform of the field strength. The measurement was performed at 4.2 mHz. Only an anti aliasing filter was used. The frequency range is, therefore, 0.39 Hz–25 kHz.
