Equi noise resista

In telecommunication, an equivalent noise resistance is a quantitative representation in resistance units of the spectral density of a noise-voltage generator, given by $R_n = frac {pi W_n}{k T_0}$ where $W_n$ is the spectral density, $k$ is the Boltzmann's constant, $T_0$ is the standard noise temperature (290 K), so $kT_0 = 4.00 imes 10^{-21},[Ws]$.

Note: The equivalent noise resistance in terms of the mean-square noise-generator voltage, e2, within a frequency increment, Δ f, is given by

$R_n = frac{e^2}{4 k T_0,Delta f}.$
