[Discuss-gnuradio] Arbitrary resampler question on gnuradio 3.7.2.1 |

Hello all,
Considering a simple gnuradio flowgraph as the following
Random source -> chunks2symbols -> complex2float -> float2complex ->
pfb_arb_resampler-> USRP sink
which used to work without any problem in the older gnuradio distributions, in
the newer 3.7.2.1 seems that the conversion above (from complex to float and
float to complex) introduces a problem, that has to do with USRP transmissions.
However, when I increased the number of taps used for the root raised cosine
filter in pfb_arb_resampler by a factor of 100, everything seems to work
properly.
Note that if the conversions float2complex and complex2float miss everything
works.
Any ideas why?
Thanks,
-George
