“…The denoising of vibration responses makes the outputs more reliable and damage can be identified with higher level of confidence in a particular structure. The literature survey shows various studies using different techniques to denoise the measured vibration signals such as statistical methods (Babajanian Bisheh et al , 2019), Kalman Filter (Xiao et al , 2020; Jin et al , 2016), Frequency response Functions (Sipple and Sanayei, 2015), Multiple Signal Classification (MUSIC) (Sharma et al , 2021), Fractional Fourier transform (Wang et al , 2012), Estimation of Signal Parameter by Rotational Invariance Technique (ESPRIT) (Sharma et al , 2021), Stockwell transform (Jha and Kolekar, 2018), Short-term Fourier transform (STFT) (Walia et al , 2015), wavelet transform (Walia et al , 2013), Hilbert–Huang Transform (HHT) (Kunwar et al , 2013; Wang et al , 2020; Sharma et al , 2021), etc.…”
