“…Many physical signals include significant noise and closely-spaced frequencies that cannot be effectively analyzed using these methods [12]. Further, real-life time series signals such as biomedical signals [38,43,30,48,8,2,[9][10][11]6,7], or vibration signals obtained from civil structure subjected to dynamic excitations [33,14,26,13,32,27] include nonlinear and non-stationary properties that cannot be adequately analyzed using these methods. In order to overcome these limitations, time-frequency representation (TFR) has become a good alternative to analyze nonlinear and non-stationary signals since a TFR can provide information about the frequencies contained in signal over time [40].…”
