How to Evaluate Equivalent Noise Temperature?

Equivalent Noise Temperature evaluator uses Temperature = (Noise Factor-1)*Room Temperature to evaluate the Temperature, The Equivalent Noise Temperature of a system is defined as the temperature at which the noise resistor has to be maintained so that by connecting this resistor to the input of a noiseless version of the system, it will produce the same amount of noise power at the system output as that produced by the actual system. Temperature is denoted by T symbol.

How to evaluate Equivalent Noise Temperature using this online evaluator? To use this online evaluator for Equivalent Noise Temperature, enter Noise Factor (N_f) & Room Temperature (T_o) and hit the calculate button.
