Hi all,

Sorry if this question has been asked before - I couldn’t find the  
answer  
after searching the web. As I would like to find out how the rational  
resampler block works in C++ (i.e. view the C++ code), I was wondering  
where  
in the GNURadio folder is the code stored.

Also, is there an official documentation page for the blocks of the  
latest  
version of GNURadio? Thank you.

Hi Chong,

perhaps you can try:  
\<gnuradio\_sources\_folder\>/gnuradio-core/src/lib/filter/gr\_pfb\_arb\_resampler\_ccf.cc

Dear Stefano,

Thank you for your guidance - I realized I downloaded the binary version  
of  
GNURadio from apt-get, which did not come with the folder gnuradio-core.  
After installing GNURadio from source I managed to find the  
corresponding  
C++ file.
