Hello,
I am using gnuradio and a usrp2 to capture samples (shorts) to a file,
that is 16 bit I and 16 bit Q.
I looked at this data in matlab and noticed that in many instances the
samples exceed 13 and 14 bits
for both positive and negative numbers (ie -12567 or +12989).
I was under the impression that a 14 bit a/d meant 13 bits plus a sign
bit so max 8191, min -8191.
Should I expect this behavior, am I interpreting something incorrectly.
If this is expected
can someone please explain. I though the rx_gain was applied before the
a/d so the max
output would be be 13 bits plus a sign bit.
Thank you,
Sharif
