Add another resistance, R3 to the circuit so that the high-frequency magnitude asymptote
is flat instead of a ¡20dB=decade. Find the minimum values of R1 and R2 so that the
phase lag between V2 and V1 at any frequency does not exceed 50±. Write the new analytic
transfer function, H(s) = V2=V1, sketch the magnitude and phase of H(s) and label the
salient features.
I think if I add a resistor in series with c2 I will put the magnitude flat.
I figured an equation for this circuit (without the extra resistor) and the actual circuit is in the attachment. I could not copy and paste it into the window so I just put it into the attachment. I know that I am suppossed to be able to change the transfer funtion into a simplier form to get the poles and zeos but I get stumped there. I ask my professor but he said "that is what grading is for" and laughed. He's the type that gives students impossible problems and is amazed that we cannot do them right way. I like him and everything, just I do not flourish under his teaching style, other than that he is a good teacer.
I know this is an algebra problem but it would really help me out to see math and not just and answer.
