Need help with calculating the gain.

1: Calculate the "raw gain" of the amplifier. Ar=Vut/Vin
2: Calculate the gain of the amplifier. Av=Vut/Vs

What is the difference between "raw gain" and gain?
Sorry for the bad translation, I don't even know if "raw gain" is the correct term in english, haha.

Thanks in advance.
 

Hello
you mean to say the voltage gain Av or Avs

the difference between Av and Avs is expressed inthe equations below
Av=V0/Vin
where Vin = (Rin / Rin+Rs). Vs

Avs = Vo/Vs

in the first equation (Av) we considering the voltage drop on the source resistance Rs while in the later one (Avs) the gain is calculated prior the source resistance drop
