    Feedback amplifier circuit redrawing

    Thanks for the answer! However I am not able to understand it... Feedback net should be a two port network.. and I can't see what are these ports. Unfortunately my textbook (and I didn't have any luck searching on other books) doesn't cover the details about identifying the topology. Thanks...

    Feedback amplifier circuit redrawing

    Given the following circuit, I need to redraw it as a Series Shunt feedback amplifier, i.e. with the following topology: Identifying the AC equivalent circuit seems to be easy: 12V and -12V become GND and current generator turns into an open circuit. However I have troubles identifying...
