How to find Cepstrum in Matlab?
To obtain both the real cepstrum and the minimum-phase reconstruction for a sequence, use [y,ym] = rceps(x) , where y is the real cepstrum and ym is the minimum phase reconstruction of x .
Cepstral analysis, rooted in speech processing and telecommunications, emerged in the mid-20th century to address challenges in analyzing complex signals, particularly human speech.
