SUMMARY

This discussion focuses on capacitively coupled RLC circuits, specifically analyzing two circuits with capacitors C and a shared coupling capacitor C'. Key concepts such as quality factor (QF) and bandwidth are essential for understanding the behavior of these circuits. The user seeks organized resources to explain how to derive the maximum voltage as a function of frequency in this setup. The discussion highlights the need for comprehensive material that covers the coupling effects and voltage measurements across different frequencies.

Homework Statement


Given a set of two capacitively coupled RLC circuits where each has a capacitor C and they share a coupling capacitor C^{'}.
I'm trying to find nice organized material that will explain the various relevant
coefficients\concepts like QF, 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.

Homework Equations


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 R_{1} for various frequencies and C^{'} coupling capacitors.

I couldn't see that image.
