Application of Fourier Transform and Wavelet Transform to Signal Fault Diagnosis
Yan Tao Tian · 2005
The application of Fourier transform and wavelet transform to signal fault diagnosis was mainly concerned. The simulation example expatiates that wavelet transform is superior to the Fourier Transform in the signal detection and wavelet Transform can make the signal detection more accurate both in time and location. The selecting principles of wavelet basis in the application of wavelet transform to signal diagnosis were then discussed.
