Signal To Noise Ratio
The equation governing the signal to noise ratio is
where
- μA is the absorption coefficient;
- In is the nonradiative contribution in electron counts/sec;
- Ib is the background contribution in electron counts/sec;
- μA is the absorption by the SEXAFS-producing element;
- μT is the total absorption by all the elements;
- Io is the incident intensity;
- n is the attenuation length;
- Ω/(4π) is the solid angle acceptance for the detector;
- εn is the nonradiative yield which is the probability that the electron will not decay radiatively and will actually get emitted as an Auger electron.

Famous quotes containing the words signal, noise and/or ratio:
“Perhaps having built a barricade when you’re sixteen provides you with a sort of safety rail. If you’ve once taken part in building one, even inadvertently, doesn’t its usually latent image reappear like a warning signal whenever you’re tempted to join the police, or support any manifestation of Law and Order?”
—Jean Genet (1910–1986)
“But what it was, alas, I cannot tell,
Because of it I had no perfect view;
But as it was, by guess, I wish it well
And will until I see the same anew.
Shadow, or she, or both, or choose you whither:
Blest be the thing that brought the shadow hither.”
—Unknown. I Heard a Noise and Wishèd for a Sight (l. 13–18)
“Official dignity tends to increase in inverse ratio to the importance of the country in which the office is held.”
—Aldous Huxley (1894–1963)
