This MATLAB exercise compares and contrasts three methods for computing the complex cepstrum of a signal whose z transform consists of a single pole system with pole radius less than one (i.e., real root inside the unit circle). The three computation methods for computing the complex cepstrum of this minimum-phase signal are the analytical method, the recursion method for a minimum-phase signal, and the conventional method based on computing the inverse Fourier transform of the complex logarithm of the Fourier transform of the signal.
