PDF	Cepstrum-Based Pitch Detection of Industrial Product Sound The detected pitch values can be used to make a distinction between different working conditions of these products such as different rotation-per- minute (rpm)

What is the formula for the cepstrum?
The real cepstrum of a signal x, sometimes called simply the cepstrum, is calculated by determining the natural logarithm of magnitude of the Fourier transform of x, then obtaining the inverse Fourier transform of the resulting sequence: c x = 1 2 π ∫ - π π log X ( e j ω ) e j ω n d ω .
How is pitch detection using cepstrum?
Cepstrum-based pitch detection uses signal periodicity.
In this case, the periodicity refers to a particular waveform of the specific length that is repeated throughout the signal, and it is reflected in a discrete spectrum containing prominent peaks equally distributed throughout the frequency range.

The cepstrum, defined as the power spectrum of the logarithm of the power spectrum, has a strong peak corresponding to the pitch period of the voiced‐speech segment being analyzed. Cepstra were calculated on a digital computer and were automatically plotted on microfilm.
