## Equivalent Noise Temperature Solution

STEP 0: Pre-Calculation Summary
Formula Used
Temperature = (Noise Factor-1)*Room Temperature
T = (Nf-1)*To
This formula uses 3 Variables
Variables Used
Temperature - (Measured in Kelvin) - Temperature is the degree or intensity of heat present in a substance or object.
Noise Factor - The Noise Factor is defined as the measure of degradation of the signal to noise ratio in a device.
Room Temperature - (Measured in Kelvin) - The Room Temperature is defined as a comfortable ambient temperature, generally taken as about 293 K.
STEP 1: Convert Input(s) to Base Unit
Noise Factor: 2.22 --> No Conversion Required
Room Temperature: 298.15 Kelvin --> 298.15 Kelvin No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
T = (Nf-1)*To --> (2.22-1)*298.15
Evaluating ... ...
T = 363.743
STEP 3: Convert Result to Output's Unit
363.743 Kelvin --> No Conversion Required
363.743 Kelvin <-- Temperature

## <Analog Noise and Power Analysis Calculators

Noise Factor
​ Go Noise Factor = (Signal Power at Input*Noise Power at Output)/(Signal Power at Output*Noise Power at Input)
Noise Power at Output of Amplifier
​ Go Noise Power at Output = Noise Power at Input*Noise Factor*Noise Power Gain
Noise Power Gain
​ Go Noise Power Gain = Signal Power at Output/Signal Power at Input
Equivalent Noise Temperature
​ Go Temperature = (Noise Factor-1)*Room Temperature

## Equivalent Noise Temperature Formula

Temperature = (Noise Factor-1)*Room Temperature
T = (Nf-1)*To

## How is noise factor calculated?

The noise factor can be derived simply by taking the SNR at the input and dividing it by the SNR at the output.

## How to Calculate Equivalent Noise Temperature?

Equivalent Noise Temperature calculator uses Temperature = (Noise Factor-1)*Room Temperature to calculate 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 calculate Equivalent Noise Temperature using this online calculator? To use this online calculator for Equivalent Noise Temperature, enter Noise Factor (Nf) & Room Temperature (To) and hit the calculate button. Here is how the Equivalent Noise Temperature calculation can be explained with given input values -> 363.743 = (2.22-1)*298.15.

### FAQ

What is Equivalent Noise 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 and is represented as T = (Nf-1)*To or Temperature = (Noise Factor-1)*Room Temperature. The Noise Factor is defined as the measure of degradation of the signal to noise ratio in a device & The Room Temperature is defined as a comfortable ambient temperature, generally taken as about 293 K.
