Is there any advantage of taking pseudoinverse of a covariance matrix?

I have found that sometimes inverse and pseudo inverse of a covariance matrix are the same whereas it is not true always. is there any relation between pseudoinverse and nonsingularity?

Take a look at the Cepstrum function. Cepstrum is straightforward when excitation are impulses and you have a good Signal-to-Noise ratio.
