This tool converts Noise Figure (NF) to Noise Factor (F).
Enter NF in dB. It should be a number greater than 0.
F = 10NF/10
NF is in dB
Noise factor (F) is defined as the degradation in Signal-to-Noise ratio due to a component in a signal chain .
F = SNRin/SNRout
Where SNRin and SNRout are the input and output Signal-to-noise ratios, respectively. F is a linear quantity.
Since the SNR at the output of a component or subsystem is always lower than at the input, the Noise Factor F > 1.
Noise factor is used in a cascaded noise analysis also known as Friis formula.
For a noise figure of 0.8 dB, the noise factor is 1.20.
