Equivalent Noise Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

Temperature = (Noise Factor-1)*Room Temperature
T = (N_f-1)*T_o
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

Noise Factor

LaTeX 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

LaTeX Go Noise Power at Output = Noise Power at Input*Noise Factor*Noise Power Gain

Noise Power Gain

LaTeX Go Noise Power Gain = Signal Power at Output/Signal Power at Input

Equivalent Noise Temperature

LaTeX Go Temperature = (Noise Factor-1)*Room Temperature

Equivalent Noise Temperature Formula

LaTeX Go

Temperature = (Noise Factor-1)*Room Temperature
T = (N_f-1)*T_o

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 (N_f) & Room Temperature (T_o) 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 = (N_f-1)*T_o 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.

How to calculate 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 is calculated using Temperature = (Noise Factor-1)*Room Temperature. To calculate Equivalent Noise Temperature, you need Noise Factor (N_f) & Room Temperature (T_o). With our tool, you need to enter the respective value for Noise Factor & Room Temperature and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.
