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.

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.
