Homework Help: Capacitively coupled RLC circuits

  1. Feb 20, 2014 #1
    1. The problem statement, all variables and given/known data
    Given a set of two capacitively coupled RLC circuits where each has a capacitor [itex]C[/itex] and they share a coupling capacitor [itex]C^{'}[/itex].
    I'm trying to find nice organized material that will explain the various relevant
    coefficients\concepts like [itex]QF[/itex], bandwidth etc. in relation to the above mentioned setup.
    Or how to find the function of the maximal voltage as the function of frequency given a certain setup.

    2. Relevant equations

    3. The attempt at a solution

    I do know how to solve the differential equations involved and get the voltage and current as the function of time but I can't find good sources that could explain all the aspects of coupling two circuits using a capacitor.

    How is the combination circuit driven?

    Does the circuit look like any of these coupled RLC circuits? https://www.google.com/search?hl=en...urce=og&sa=N&tab=wi&ei=pnUGU-q6Ec_poATJqYHgAQ

    It looks like this:


    And the we've measured the voltage on the [itex]R_{1}[/itex] for various frequencies and [itex]C^{'}[/itex] coupling capacitors.
