Dear List,

I'm looking to convert my second order Direct Form IIR filter structur
over to an equivalent second order Lattice Ladder filter structure. Doe
anyone know of a good reference or link which details how to implemen
such a beast?

Thanks for any information.

Best Regards,
David Ross

Hi David,

We had a problem involving 2nd-order IIR lattice filters for
homework in our DSP class. Here's what I handed in:

in the latest JAES (November) Orfanidis did a treatise for IIR EQ filters
that included Ladder implementations.

dunno if that helps or not.

Thankyou both, that does help a lot. Randy I will check out your code late
- perfect, matlab and C :-)

RBJ, thanks, I will look into the Orfanidis Paper. I love the Orfanidi
books, really readable, understandable and come with good examples, s
hopefully this paper will be similar.

Cheers,
David

Digital Signal Processing by Sanjit K. Mitra has a lot of info on filter
structures, including some lattice structures. I found this book at my
local university.

This is a relatively new book (or at least a new edition). I think its one
of the better books I've seen (I have about 50 DSP books)

I agree 100 percent. Mitra seems to cover a lot of
important topics well. It's now one of my top DSP
books, behind Proakis/Manolakis only.

Apparently they have recently begun reprinting
the 2nd edition. When I bought the book about
a year ago, new was not available. At $250
it is quite expensive, though!

Was it used or new? Are you sure it's not 2e? I don't see the 3e at
either Booksamillion or Amazon, and Booksamillion is selling 2e for
$250!

Absolutely! It's written on the outside jacket

The ISBN is 0-07-286546-6, Component of ISBN 0-07-304837-2 (maybe when it
includes the CD?)

One interesting note is that the copyright is 2006. I'm fairly sure that
my DeLorean is missing a flux capacitor, so I don't understand how I
could have obtained the book.
