<BLOCKQUOTE>Calulate cepstral coefficients from lpc coefficients.

<P>It is possible to calculate a set of cepstral coefficients from
lpc coefficients using the relationship: 

<P><BR><CENTER><IMG BORDER=0 SRC=g000029.gif><BR></CENTER>

<P>The order of the cepstral analysis can be different from the lpc
order. If the cepstral order is greater, interpolation is used (FINISH
add equation). Both orders are taken from the lengths of the
respective vectors.  Note that these cepstral coefficients take on the
assumptions (and errors) of the lpc model and hence will not be the
same as cepstral coefficients calculated using DFT functions.
