Homework Help: Transform Function / Bode

  1. Jun 4, 2008 #1
    While getting ready for my final exam, I came across this exercice that I got lost in.


    So I have to first find the transform function, then the response for a unit-input, and then a harmonic input (sinusoidal) with w=314rad/s, and finally the bode's plot.

    I started like this for the transf function :

    First I need the differential equation...

    Vi = Vo + Vr = Vi + Ri1 = Vs + Ri - Ri2 = Vi + Ri - Rc1 dVc/dt

    Now I don't know how to take off Vc to only leave Vi and Vs .. So i'm stuck here !!
    Please help and guide me through this exercice !

    P.S. Sorry for my bad English :]
