I find the example at the online page http://gnuradio.org/doc/doxygen/page_pfb.html very helpful (code at the end of the page). It runs and generates nice plots. Still trying to get used to it.
But the code at gr-filter/python/pfb.py does not run. It appears to be a module? How do I run it or use it? Also what does gr-filter/python/qa_pfb_channelizer.py do? Some of this trace to pfb_channelizer_ccf.cc code? What does "blks2" relate to this and other examples?
