    Zastosowanie transformaty falkowej do określenia defektów pali
    (Wydawnictwa AGH, 2010) Wrana, Bogumił; Czado, Bartłomiej
    In this paper, a method is described for the non-destructive testing (NDT) signals by employing wavelet transform in the time-frequency plane. Wavelet analysis is a mathematical technique and a new signal-process tool that allows the signal to be viewed in the wavelet time-frequency domain. The main goal of this paper is to discuss the feasibility to used CWT methods in the time-frequency domain to sonic echo signal in piles. The results show that such an approach may provide a more complete way of viewing the signal.
