"An Amplifier with an R = 10k ohms and R = 0.1 ohms has a voltage gain of 66 dB and a noise figure of 12 dB. If the input signal voltage is 20µV and the output noise voltage is 100µV."
a) Find the output S/N
b) Find the input noise voltage
c) Find the voltage gain"
Anyone took a telecomm. class before? I have this:
I'm confused to how that I had the following numbers to begin with:
Av = 66dB
NP = 12dB
Ri = 10k ohms
Ro = .01 ohms
Eno = 160µV
20µV, is this Esi? If so, why is the Esi = 2µV? Did I write it down wrong?
...that one can get the rest, can someone let me know how? I know the Si/So because it has a formula.
