Abstract :
A technique based on fitting splines to the phase derivative curve is presented for the efficient and reliable computation of the complex cepstrum. The frequency sampling and the thresholds of the adaptive phase unwrapping algorithm are studied as a function of the radii of the zeros of the signal.
