“…The normalized power index is defined as an idea of the locations of the different regions which we here refer to as "burst" and "background". The burst region corresponds to the main BN signal, while the background corresponds mainly to the higher field region where Barkhausen noise is not observed 16,17 . This subdivision is important for the index we define in the next section.…”

“…Το σήμα του μαγνητικού θορύβου Barkhausen ως προς το χρόνο, μπορεί να αναλυθεί, μέσω κατάλληλων λογισμικών (MATLAB ® , LabView ® ) και να προκύψει ένα σύνολο επιπρόσθετων μαγνητικών παραμέτρων [110]. Συγκεκριμένα, ο γεωμετρικός τόπος των σημείων πάνω από ένα κατώφλι δυναμικής ενέργειας, δηλαδή πάνω από μια ελάχιστη τιμή τάσεως (threshold) θεωρείται ότι περιλαμβάνει μαγνητικά γεγονότα (counts), ενώ οι κορυφές του μαγνητικού σήματος χαρακτηρίζονται ως γεγονότα (events) (εικόνα 2-13).…”

“…Tensão de Barkhausen em função do campo magnético para amostras com diferentes quantidades de deformação.Um artigo recente[69] também relata uma estrutura de dois picos para amostra não deformada. Essa estrutura inicial teve sua forma modificada após pequenas deformações no sentido de se formar uma curva com um único pico para as deformações mais elevadas.…”
