A combined generalized Warblet transform and second order synchroextracting transform for analyzing nonstationary signals of rotating machinery

Abstract In recent years, considerable attention has been paid in time–frequency analysis (TFA) methods, which is an effective technology in processing the vibration signal of rotating machinery. However, TFA techniques are not sufficient to handle signals having a strong non-stationary characterist...
