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:
{1 + \sum_{k=1}^{N} a_k z^{-k}}

Thanks for the feedback!
