SOUND AND VIBRATION SIGNAL ANALYSIS USING IMPROVED SHORT-TIME FOURIER REPRESENTATION
Time-frequency imaging provides a straightforward means to understanding machinery conditions. The methods of short-time Fourier transform (STFT), Wigner-Ville distribution (WVD) and smooth-windowed Wigner-Ville distribution (SWWVD) are applied to the condition monitoring of rotating machines. The s...
