Hello,
Which version of GR are you running in Windows? Previous versions were not
compatible with the filter designer.
Also, could you give us a screenshot of your GRC flow graph?

Hello
I 'm an old french Applied Physics Teacher and I try to use basic GRC for
my electronics students (2 first University years in a technical Department)
as a learning tool since 2016
I use GRC under Pentoo Linux if I need to run HackRFone/osmocom and/or
DBTVstick/RTLSDR
Does anyone have a working example of the IIR filter block in GNU
Radio Companion that I can see, and the filter designer app, table, or
equation which generated the coefficients?
Could you try grc files attached in
http://lists.gnu.org/archive/html/discuss-gnuradio/2012-08/msg00128.html. I
Thanks for the example links, they were very helpful. There were two
things I was doing wrong: First I didn't use square brackets for the
sets, and to use the biquad calculator featured on earlevel.com, the B
coefficients needed to start with a 1.0 filler and the rest negated
like this:
I just pushed a branch to my github repo called iir_filter that
implements the optional argument to the IIR filter as we discussed.
The default is oldstyle=True and doesn't change any behavior. If you
set this to False, you can directly copy taps from programs like

Hi all,
So we're working towards integrating the new gr_filter_design tool
that Sreeraj built this summer for our GSoC project. One issue has
come up with it is the specification of the IIR filter taps and how
they are used in GNU Radio. To summarize the conversation between
Sreeraj and myself:

GNU Radio's expected transfer function:
H(z) = \ frac{\sum_{k=0}^{M} b_k z^{-k}}{1 - \sum_{k=1}^{N} a_k z^{-k}}
But gr_filter_design gives the denominator (a_k) in the form:

Hi, How is the iir_filter_ffd module used? If I give 3 feedforwardtaps
b0,b1,b2 and 2 feedback taps a1,a2 will I get transferfunction (b0 + b1 z^-1
+ b2 z^-2) / (1 + a1 z^-1 + a2 z^-2)?

If your FFT is 1024 wide, then you essentially have 1024 single-pole IIR
filters, each computing the
low-pass filtered version of the individual bins. This is called (at
by me) spectral averaging.
There will
