    Hi guys. Can anyone help me answer this question, I was looking at examples but I couldn't figure out how to answer the questions, or draw the A network, as the question circuit is really different from the examples I found online

    Would appreciate if someone helped me understand and do the problem:)

    What is a "voltage-sampling shunt-mixing network"? :confused:

    I looked it up and it's another way of saying Shunt-Shunt

    Thanks, seems like it's mostly the same circuit just with different variables.

    Could you tell me which one is the β network, I have to circle it in the picture

    Which resistor is the feedback resistor ?

    The feedback network I guess? Like it shows in the PDF that you linked me to

    In the OP's question 'β' probably refers to the feedback fraction, because the universal feedback equation is often written:
    A(closed loop) = A/(1+Aβ)
    This should not be confused with the hfe or 'β' of a bipolar transistor.

    The feedback fraction is the amount of output voltage that is fed back to the input, so it is the gain of the potential divider formed by the feedback resistor and input resistor.
