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 22.214.171.124 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
Any ideas why?
