Yes indeed it 's a very simple technique , you just take your spectrum and  and use whatever is coming from FFT ,  add constant ,
Hmm.
you know ? on  onto power spectrum. That  that  Or the other thing is of course if you have a spectrum , what you can s start doing , you can leave  start leaving out the p the parts which are uh uh low in energy and then perhaps uh one could try to find a  a all - pole model to such a spectrum. Because a all - pole model will still try to  to  to put the  the continuation basically of the  of the model into these parts where the issue set to zero. That 's what we want to try. I have a visitor from Brno. He 's a  kind of like young faculty. pretty hard - working so he  so he 's  so he 's looking into that.
Hmm.
