Conclusion
DIFFERENCES
Expression
Noise Factor is a linear ratio, while Noise
Figure is the logarithmic (dB) representation
of that ratio.
Interpretation
Noise Figure is more commonly used in
practical applications because it provides a
more intuitive understanding of the noise
performance of a device, especially when
dealing with multiple stages of amplification
or components in a system.
Calculation
While both measure the same phenomenon
(degradation of SNR), Noise Figure is derived
from the Noise Factor through a logarithmic
transformation, making it easier to work with
in calculations involving gains and losses in
decibels.
