[Discuss-gnuradio] question about xlating filter and resample filter

[James Jordan]

Hi all, I use xlating filter get baseband data from a wide band signal, but the xlating result sample
rate is not what I want, so I need to use resample to convert the signal to the sample rate what I 
want. I find gr_rational_resampler_base_ccc also need a filter(tap). I already filter the baseband signal
so how should I set the resampler filter(tap)?

Thanks!
