### What is Meant by Effective Noise Temperature?

In physics, the effective noise temperature is defined as the temperature of the resistor in which the noise power is equal to that of the circuit or the device. The effective noise temperature is mostly used in the telecommunication fields. The effective noise temperature can be calculated using the formula

T = N/kB

Where,

N represents the noise power within the specified bandwidth B

K represents the Boltzmann’s constant which is approximately equal to the value 1.38×10-23JK-1
