Transfer function for electrical circuit

  1. May 21, 2012 #1
    Hello!

    I have a problem to get a transfer function from my circuit(this circuit is marked with question sign "?").
    For upper circuit this function is calculated...this can be seen in image.

    I tought that it would be easier to get transfer function by using matrix, so then W(s) = 1/a11 By doing that I get W(s) = 1/C1*s*R1+C2*s*(R1+(C1*s*R1+1)*R2

    I would be very thankful if someone could me with this exercise.

    To calculate transfer function you basically need to compute Vout/Vin. Introduce a variable V for the intermediate node, and apply KCL equations and eliminate V to obtain a relation between Vout and Vin.
