High signal-to-noise ratio
WebMay 13, 2024 · Rnoise stage 1 = 50 ohms Rnoise stage 2 = 5,000 ohms (gain1^2 * Rnoise stage 1) Rnoise stage 3 = 500,000 ohms (gain2^2 * Rnoise stage 2) Simply stated, even a moderate gain of stage 1 (preamplifier) greatly eases random noise design of later stages, by the SQUARE of stage1 gain. WebSep 1, 2016 · So the signal-to-noise ratio is 100/10 = 10. If we collect 10,000 photons, the noise is 100 (100 is the square root of 10,000), and the signal-to-noise ratio is now 10,000/100 = 100. This higher signal-to-noise ratio will produce a much better image even though, technically, it has more noise. We can collect more photons with either longer ...
