Re: Unexpected issue with file source and USRP source

demodulator chain blocks are causing back pressure due to taking too
much time
in processing but when run in real time it causes data loss during
exchange of
samples between blocks.? I am confused if in real time the
gr_pfb_clock_sync_ccf block or any other major block stucks in processing
during which samples are lost due to new incoming samples.

Are you observing overflows? If so, have you tried reducing the
bandwidth and see if that helps?

Thanks for your reply. I am not observing any overflows. I am using 500k
sample rate. My system specs are 6GB RAM core i7 ubuntu 12.04.

What could be the issue ?

Regards.
