In telecommunication, an equivalent noise resistance is a quantitative representation Equivalent noise resistance 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 .
Note: The equivalent noise resistance in terms of the mean-square noise-generator voltage, e2, within a frequency increment,Δf, is given by .

Electronics Topics
The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
