Effective Noise Temperature Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective Noise Temperature = (Overall Noise Figure-1)*Noise Temperature Network 1
T_e = (F_o-1)*T_o
This formula uses 3 Variables

Variables Used

Effective Noise Temperature - (Measured in Kelvin) - Effective Noise Temperature represents the equivalent temperature of noise that, would produce the same amount of noise power as the actual devices or components in the system.
Overall Noise Figure - (Measured in Decibel) - Overall Noise Figure quantifies how much the device degrades the signal-to-noise ratio (SNR) of the input signal as it passes through the system.
Noise Temperature Network 1 - (Measured in Kelvin) - Noise Temperature Network 1 defined as the temperature at the input of the network which would account for the noise ΔN at the output.

STEP 1: Convert Input(s) to Base Unit

Overall Noise Figure: 1.169 Decibel --> 1.169 Decibel No Conversion Required
Noise Temperature Network 1: 177.51 Kelvin --> 177.51 Kelvin No Conversion Required
