Failure of the amplifier to pull photons from the background noise.Not even close to explaining your statement which was (and I'll add some emphasis)... "FAILURE of the amplifier to PULL photons from the background noise". All you've done is tell us with your analogy that for low signal levels the SNR would be high. Please enlighten us how even the best amplifier in the world, even a hypothetically perfect amplifier, will "PULL photons from the background noise".
But wait, he stated,I am quite done with this.
