Hi Ben,
I have implemented a function to dynamically change my system gain based
on sample distribution (to utilize full range of A/D converter). However
I'm wondering why the sample values have a dependance on sample rate.

Hi Simon -
Just to make sure I'm understanding your question correctly: are you
asking how to dynamically change your system gain or scale your
samples so that you are using the full range [-1, +1]?
Cheers,
Ben

Hi,
In my GNURadio program I need to determine the correct gain in
order to fully utilize the dynamic range of the A/D converter of
the Ettus USRP x310.
I currently have implemented a automatic function for this using
the probe samples block and make sure that values stays just
within -1 > +1. I.e I check the distribution and make sure a
certain percentage of the values doesnt go above a threshold value.
However the values seems to have a dependence on sample rates, how
should I think here? Anyone else that have implemented this using
the probe block, what was your method?
Best regards
Simon
