LECTURE ON CEPSTRUM AN ALYSIS. N.MORGAN / B.GOLD. LECTURE 21 Cepstrum Analysis. Lecture 21 ... •Complex Cepstrum : DFT of the log of the DFT of a signal.
11 oct. 2021 equivalently we can take DFT of log Y [k] and process in frequency domain cepstrum is the DFT (or DCT) of the log spectrum ...
Then DFT (discrete Fourier transform) is used to transform the cepstrum coefficients back to the spectrum domain to obtain a smoothed spectrum curve.
Cepstrum has found that frequency of such signal is 0.01188 Hz which means that Idea behind cepstrum is to look at such periodic DFT as if it is some ...
