Wavelet Integrated with Fourier Transform: A Unified Technique
Fourier transform-based spectral analysis has been widely applied to processing signals, such as vibration and acoustic signals (Mori et al. 1996; Tandon and Choudhury 1999; Cavacece and Introini 2002), acquired from manufacturing systems. Because of noise contamination and signal interference, the constituent components of interest may be submerged in the signal and difficult to be revealed through a spectral analysis (Ho and Randall 2000).
