Lecture 12: Noise in Communication Systems
rfic.eecs.berkeley.eduTotal Input Noise for Cascade By definition, the noise added by each amplifier to the input is given by Namp,i = Ns(F −1) where Ns represents some standard input noise. If we now input refer all the noise in the system we have N′ amp,i = Ns(F1 −1)+ Ns(F2 −1) G1 Which gives us the total noise figure of the amplifier F = 1+ N′ amp,i ...
Noise level calculations How do you add noise levels?
www.hoevelakenbereikbaar.nl0–1 dB then add 3 dB to the higher level to give the total noise level. 2–3 dB then add 2 dB to the higher level to give the total noise level. 4–9 dB then add 1 dB to the higher level to give the total noise level. 10 dB and over, then the noise level is unchanged (i.e. the higher level is the total level) So, 35 dB plus 35 dB equals 38 dB.
