[hpsdr] Mercury Noise/Sensitivity

[Gerd Loch]

Hi,
there is a fundmental calculation for the receive sensitivity in the Mercury
Wiki based on noise figures for the ADC LTC2208. There is no dependency on
the bit resolution of the ADC in the calculation.

I wonder which influence the bit resolution has on the sensitivity. 16 bit
resolution of a full scale signal of 1,5V means 22uV. Does this mean that
the minimal discernible voltage is 22uV?

What would be the result if the ADC had only i.e. 10 bit resolution?
