Random signal and noise calculator

$$ e _n=√(4 K T R △f) $$

• e---root mean square (RMS) of noise voltage
• T---temperature, unit Kelvin (K)
• R---resistance, unit ohms (Ω)  * f--- Frequency of noise broadband, in Hertz (Hz)  * k---Bertzmann constant, unit J/K

Note the conversion Celsius Kelvin

$$ T _K = 273.15℃ + T _C $$

Note:

The sign of the Boltzmann's constant is expressed as k or kB. It illustrates the relationship between absolute temperature and the kinetic energy of each molecule in an ideal gas. This constant is named by the Australian physicist Ludwig Boltzmann (1844-1906). It is the ratio of the gas constant to the Avogadro's constant. The value of the Boltzmann constant is approximately equal to 1.3807 x 10^-23, and each Joule is open (J·K^-1)
