Web\$\begingroup\$ The SNR of the input is always higher than the output as the gain of both input signal and noise is the same plus added noise of the amplifier. So a low noise factor adds as little noise as possible to get as close to ratio=1 as possible. Noise Figure is the 10*log version of the linear Noise Factor. WebDec 10, 2009 · Even if you have a low-noise (NF=noise figure) input amplifier, excessive noise between amplifier stages will [STRIKE]increase [/STRIKE] decrease the SNR. If a low NF input amplifier has 10 dB gain, and the second amplifier has a high NF, the SNR will be reduced. In this case, increasing input amplifier gain will improve SNR.
