ANALYSIS OF NOISE-LIKE SIGNALS OF ACOUSTIC EMISSION METHODS BROADBAND FILTERING
(pp. 49-56)

Abstract. The work summarizes the experience of broadband analysis of signals of acoustic emission (AE). The main aim of the work consists in the use of filters of a special shape, which are images of the permanent presence of noise from background physical processes. The proposed approach allows: to reduce noise in the signal AE and to increase the signal to noise ratio; to assess the influence of the path propagation on the distortion of AE; to use as filters AE signals from background processes; to provide sensitive frequency spectrum of the investigated process.

Keywords: acoustic emission, pseudonoise signals, noise reduction, diagnostics.
