Cepstrum Analysis and Gearbox Fault Diagnosis
Cepstrum Analysis is a tool for the detection of periodicity in a frequency spectrum and seems so far to have been used mainly in speech analysis for voice

Concept of Cepstrum
The frequency of this ripple can then easily be determined by calculating the spectrum of the logarithm spectrum (amplitude) or it is manifested by a peak. In
A Discrete-cepstrum Based Spectrum-envelope Estimation Scheme
Abstract. Approximating a spectral envelope via regularized discrete cepstrum coefficients has been proposed by previous researchers.

A History of Cepstrum Analysis and its Application to Mechanical
By retaining the phase in all operations the “complex cepstrum” was defined as the inverse Fourier transform of the complex logarithm of the complex spectrum
