Howtosignalprocessing
SNR = signal / noise = S / N. A signal-to-noise ratio of 10, for example, implies that the noise is one tenth of the signal. Hence the size of the error bar is 10%. The SNR required for an astronomical observation depends on the scale of the feature being studied.

How do you calculate signal-to-noise ratio?
So, for complex calculations, you divide the value of the desired signal by the amount of the noise and then take the common logarithm of the result, i.e., log (S ÷ N). After this, if the signal strength measurements are in watts (power), you will then multiply by 20.
What is signal-to-noise ratio in astrophotography?
If we count 100 photons, we have a count of 10 for the noise (10 is the square root of 100). 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.
How do you calculate signal-to-noise ratio chromatogram?
Calculating Signal to Noise Ratio
Most commonly used generic formula for Signal to Noise = 2*Peak Height/Noise. For such calculation, two possible approaches exist: The Noise is determined from the same chromatogram within area with no peaks.
