Hello, I am looking for algorithms to calculate a minimum phase FIR filter from a desired frequency responce or from zero phase impulse response. Thank you, Frederic

Google is your friend: http://groups.google.com/groups?as_q=minimum%20phase%20FIR&as_ugroup=comp.dsp&lr=&hl=en I also believe that there is an entry in the comp.dsp FAQ.

Thank you all, I have found the FAQ at http://www.bdti.com/faq/dsp_faq.htm Since calculation methods are clearly explained, I presume that code should exist. --------------------------------------------------------------------------- "Matthew Donadio" <m.p.donadio@ieee.org> a �crit dans le message de news:pan.2003.09.17.01.25.48.374233@ieee.org...> On Tue, 16 Sep 2003 21:03:49 +0000, Erik de Castro Lopo wrote: > > Frederic Le Bas wrote: > >> I am looking for algorithms to calculate a minimum phase FIR filterfrom a> >> desired frequency responce or from zero phase impulse response. > > > > This has been covered many times in this group.
