Homework Help: How do we find the frequency response for a circuit

  1. May 11, 2007 #1
    1. The problem statement, all variables and given/known data

    How do we find the frequency response for a circuit (RLC / transformer ckt)?

    If i have its
    * resonant frequency
    * Q factor
    * bandwidth

    2. Relevant equations

    just a general question

    3. The attempt at a solution

    like my other post but i have all the answers to the first parts - just need a method to find the frequency response.

    thanks in advance

    Although I'm sure there is some shortcut way of doing it since you know those three quantities, I don't remember the intricacies of RLC circuits, so I'll just point out that the circuit is probably simple enough that you can calculate the transfer function in the frequency domain (or in the Laplace domain), by brute force, i.e. by writing down the impedances of the elements and then calculating the transfer function Vout/Vin algebraically.
