Equivalent noise resistance
From Wikipedia, the free encyclopedia
In telecommunication, an equivalent noise resistance is a quantitative representation in resistance units of the spectral density of a noise-voltage generator, given by 
where Wn is the spectral density, k is the Boltzmann's constant, T0 is the standard noise temperature (290 K), so ![kT_0 = 4.00 \times 10^{-21}\,[Ws]](../../../math/b/e/e/beebc5cdad8078f45438d3b280cf124c.png)
.
Note: The equivalent noise resistance in terms of the mean-square noise-generator voltage, e2, within a frequency increment, Δ f, is given by
