Homework Help: Voltage transfer functuon of network

  1. Jun 11, 2013 #1
    I dont have access to computer right now so heres the link to my working

    According to the answer I shouldnt have (s/RC) term on the numerator, otherwise all good.

    Can anyone please point out where i have gone wrong?

    You are going to post your image sideways to make it hard to read? I'm not going to bother.

    [STRIKE]Your math looks okay to me. The s/RC term should be there.[/STRIKE]

    EDIT: I take that back! When you converted the first resistor and capacitor to impedance Z, you didn't also adjust V1 accordingly. Essentially you are taking the Thevenin equivalent of v1 and the first R/C section. You need to find both the Thevenin impedance Z and the Thevenin voltage that replaces V1.

    A strange approach, trying to replace the first R-C section with a series-Z.

    Why not just write nodal equations?
