“…Therefore, the WT can extract information in the time domain with reference to different frequency bands. This simultaneous time-frequency decomposition gives the WT a special advantage over the traditional Fourier transform in analysing non-stationary signals [31,32,33]. …”

“…The main procedures for signal features extraction which are typically used in sensor monitoring research can be classified as follows: time-domain methods (e.g., principal component analysis (PCA)) [21,22,23]), frequency domain methods (e.g., fast Fourier transform (FFT)) [20,30]) and time-frequency domain methods (e.g., wavelet transform (WT) [31,32,33]).…”

“…However, an experimental way cannot be the only technique for investigating all possible combinations of operating parameters due to high costs and time spent for determining the optimal values. Mathematical modeling of a physical system employing numerical methods has become an effective alternative (Bogdevičius and Vitkūnas 2016;Andrikaitis and Fedaravičius 2014;Najafi and Ahmadzadeh 2014;Skrickij et al 2016;Spruogis et al 2015;Dyakov and Prentkovskis 2008;Moezi et al 2015;Bogdevičius et al 2015;Dönmez Demir et al 2015;Khatir et al 2014;Ahmadi et al 2015;Zhang et al 2015;Simonović 2015;Allali et al 2015). The paper is aimed on proposing mathematical model for the pneumatic damping system.…”

“…For investigation, the following diagnostic parameters were employed: X1 -Peak, X2 -Peak to Peak, X3 -RMS. Usage of these parameters gives good diagnostic results and minimal number of faulty diagnosis [28].…”

“…If compared to STFT, Wavelet uses narrow time windows at high frequencies and wide time windows at low frequencies, using Wavelet transform computing time is decreasing. Skrickij et al [28] showed that using wavelet transform and an extended frequency range, AE and VS signal monitoring of the gear unit is much more sensitive, and the occurrence of teeth faults and their growth can be recognized at an earlier stage.…”
