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 is the spectral density, is the Boltzmann's constant, is the standard noise temperature (290 K), so .

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