Hello,
I was studying the code of the rational resampler block in
gnuradio/gr-filter/pythoin/rational_resampler.py and I have a doubt
about the low pass filter generated by the design_filter() function.
It seems that the generated filter does not take into account the
decimation factor. Is that correct? I don't see how this may result in
the correct anti-aliasing filter when it is applied by
rational_resampler_base_xxx.
Can someone point me to a relevant explanation?
Thanks a lot. Cheers,
Daniele
