[Discuss-gnuradio] gr_rational_resampler_base_XXX query

Dear All,

 

I have a question in gr_rational_resampler_base_XXX.cc module.

 

1. I got 2040 samples instead of 2048 or 2060 samples instead of 2048. Shall I use this module for interpolation and decimation? Or any other suitable module is available?

 

2. In function

 

 void

@NAME@::install_taps (const std::vector<@TAP_TYPE@> &taps)

{

  int nfilters = interpolation ();

  int nt = taps.size () / nfilters;

 

  assert (nt * nfilters == (int) taps.size ());

 

  std::vector< std::vector <@TAP_TYPE@> > xtaps (nfilters);

 

  for (int n = 0; n < nfilters; n++)

    xtaps[n].resize (nt); 

 

  for (int i = 0; i < (int) taps.size(); i++)

    xtaps[i % nfilters][i / nfilters] = taps[i];  ----------à How to calculate taps[i] value here. Any table or module?

 

  for (int n = 0; n < nfilters; n++)

    d_firs[n]->set_taps (xtaps[n]);

 

  set_history (nt);

  d_updated = false;

 

 

 

Thanks in advance

 

 

Regards,
