  When we do cepstral analysis, dose y-axis still represent magnitude (while having x axis as quefrency)?

  The vertical axis on the cepstrum is the value of the cepstral co-efficients. It could be labelled “amplitude” or “magnitude”. Sometimes we use the absolute magnitude for the purposes of plotting so that everything is positive.
