Thermal noise is generated by the conversion of electric energy into electromagnetic energy (radio, F, light, and UV radiation). This can be associated to resistance and is calculated by the next formula:
Where:
Pn is the power noise in watts (W)
k is Boltzmann´s constant = 1,38 x 10-23 Ws/oK
T is the temperature in degrees Kelvin (oK)
Δf is the bandwidth in hertz (Hz)
