IC for Self Tuning RCL Circuit Design

Hello,

 

I'm trying to build an RCL measuring circuit for high-impedance RCL circuit analysis. I'm thinking of using an Atmega 382P-Arduino set up, since it looks like it will be agood fit for my needs.

 

Anway, I have a good grasp on how I want to project to run, I just have a small problem.

 

I would like to have a voltage divider that will tell me the frequency of the RCL between input pulses from the buffer and a voltage divider that will tell me the average self-frequency.

 

If I want to run Atmega synchronously, I will need a clock divider to run it off a 100MHz to 1Ghz clock. If I wire it asynchronously, I will need to use a buffer so it puts in a value of when the pulse event has to occur in time and the time it has to happen at.

 

What would be the best approach to this issue? An IC perhaps?

 

Any thoughts are welcome.

 

Thanks!
