[Discuss-gnuradio] Filter in rational resampler

[Daniele Nicolodi]

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
