WebSNR as you know means Signal-to-Noise ratio. So it's 20 l o g ( V S V N ), where V S is signal voltage and V N is noise voltage. So, if noise ( V N) is really small (compared to signal), then SNR gets really big. It's quite possible to have systems with negative SNR (where the signal level is less than the noise), where you need synchronous ...
