Forum: GNU Radio gr_filter_design

Has anyone successfully used gr_filter_design to design high-pass IIR
filters?

If I plug the generated coeffs into the IIR filter in GRC, it faults
with a NaN error at runtime.

Low pass is fine.

I assume you're talking about the new filter design tool out of the 
GSoC?
