The level of aliasing in the computation of the cepstrum (real or complex) is estimated by comparing the results of the analytical method (based on finding the roots of the numerator polynomial of a window-weighted frame of speech, with the results for computation of the cepstrum using finite size FFTs. By increasing the size of the FFT used to compute the cepstrum, the level of aliasing decreases. The file '3.13 Cepstrum aliasing.pdf' provides a User's Guide for this exercise.
