    Ucc= 16v
    Source impedance (Rs) = 25 ohms
    Amplification factor (B) = 100
    R base <- emitter = 25 ohms
    Verify amplification condition > 20

    I think it is a radio amplification problem
    I know only formullas for tension amplification

    Ummm... Seems like it's given.

    I'm guessing that they are looking for the effects of input loading due to the finite source impedance and the input resistance. But I don't know exactly what they mean by the notation "R base <- emitter".

    But a more fundamental problem is that the TS is apparently guess what the basic kind of problem is and then only bringing a bunch of formulas to the table.

    - means resistance seen towards the base
