Based on the circuit design shown, I am supposed to find the following: 1)D.C. and A.C. load lines 2) What happens to Av, Gv, Ai, and Gi when Rc changes. 3)max value of Rc and why? 4) min value of Rc and why? 5) What happens Av, Gv, Ai, Gi, hie, and ro when Rb changes? 6) max value of Rb and why? 7) min value of Rb and why? I've managed to find everything but the max and min values of Rc and Rb. I found that Av max is equal to -Vcc/VT so I did find a max value of Rc and a min value of Rb that sets Av at its max value but I'm not even positive if that is correct and I have no idea about the min value of Rc and max value of Rb. Is there a minimum value of Ai or Av? Or am I completely off in my pursuit of this question?
