Swig stuff are python bindings to C or C++ code. So in your example pfb_clock_sync_ccf() has been coded in C++, and _digital_swig.pfb_clock_sync_ccf() is the generated python wrapper to access the C++ pfb_clock_sync_ccf() from a python script.

Thanks for clearing up what _digital_swig was. I was able to do a search in my gnuradio folder for pfb_clock_sync_ccf and map_bb and found the header and source files. Cheers, Frederick
