cepstrum
cepstrum calculation
Calling Sequence
fresp = cepstrum(w,mag)
Arguments
- w
positive real vector of frequencies (rad/sec)
- mag
real vector of magnitudes (same size as
w
)- fresp
complex vector
Description
fresp = cepstrum(w,mag)
returns a frequency response fresp(i)
whose magnitude at frequency w(i)
equals mag(i)
and such
that the phase of freq
corresponds to a stable and minimum phase
system. w
needs not to be sorted, but minimal entry should not be
close to zero and all the entries of w
should be different.
