Least-Squares Approximation of FIR by IIR Digital Filters
in [Matlab]
|
From: Kenneth Faller II on 2 Apr 2010 10:59 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. John
