Least-Squares Approximation of FIR by IIR Digital Filters

Discussion in 'MATLAB' started by Kenneth Faller II, Apr 2, 2010.

  1. Hello,

    I am trying to implement an algorithm described in the following paper:

    H. Brandenstein and R. Unbehauen, Least-squares approximation of FIR by IIR digital filters, IEEE Trans. Signal Process. 46 (1998), pp. 21–30.

    I found part of the code on the author's university website (http://www.acoustics.hut.fi/software/kautz/kautz.htm). There is a file called braun1.m that codes Section IV from the paper. Can't figure out the other part (Section III of the paper).

    Any help would be appreciated.

    Hi Kenneth,

    My name is Chandra. I have been working on the same problem as you. While I have developed my own method of obtaining denominator, I have so far not been able to get the numerator for the IIR. I find the write up in the papers I have seen to be very confusing. Any pointers?
