[Discuss-gnuradio] IIR Filter taps

2012-11-19 Thread Tom Rondeau
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:

Which version of Ice does the controlport branch currently depend on? I only ask because I think only Ubuntu 12.04 and 11.10 have Ice 3.4.2, whereas older Ubuntu versions come with the Ice 3.3.x versions and there are significant API changes between the two, so the apt-get install may only be

Hi Brooke, are you mixing hand-edited code and files generated by gr_modtool? Also, can you manually import howto_swig from the build/swig dir? Besides, if you're getting started, 3.6.0 is not the newest version of GNU Radio. MB On Mon, Nov 19, 2012 at 03:08:50PM -0500, Brooke Hayden wrote:
