Dear all,
I have questions regarding to the relations betw SNR and receiver gains (digital and analog):
We have a system that allows us to set the analog receiver gain (ARG) and digital receiver gain (DRG). The signal doubles if we increase one integer of either ARG or DRG (eg from 12 to 13), and the filling factor of ADC also doubles (eg from 45% to 90%). My question is: Whether the SNR changes or not in this case? We tested but could not confirm.
Thanks!
Charles
