Application Notes - Gearbox Analysis using Cepstrum Analysis and
The cepstrum and the auto-corre- lation are closely related. The main difference is that the inverse FFT is performed on the logarithm of the power spectrum as
L9: Cepstral analysis
The cepstrum is defined as the inverse DFT of the log magnitude of the. DFT of a signal For a windowed frame of speech the cepstrum is.
Cepstrum Analysis
be easily obtained by filtering in the pseudo-frequency domain. In summary after taking the inverse z-transform and obtaining the power cepstrum
Cepstral Analysis
Let x(t) be a time signal and Fx(?) its Fourier transform; by definition the complex cepstrum Cx(t) is the inverse Fourier transform denoted F-1
