OP AMP Gain for complex circuit

Bandit03 said:

Can someone verify the gain of this op amp circuit?
The frequencies I will be testing the circuit at are 1, 10, 100 and 500 Hz.
I would like to know the method and values of the theoretical gain.
The circuit diagram is in the attachment.
Values are
R14 = 3570
R15 = 57600
R16 = 2320
R17 = 59000
C3 = 0.000000033 Farads
C4 = 0.000001 Farads
L1 = 6 Henries

NO, I am a mechanical engineer and I am trying to understand this op amp circuit in our test stand.

I will need some time to disect, but generally yes.
What program did you use to do the analysis?

The plots looks accurate since the resonant frequency is 64 Hz.

Thanks for your help, the plots should help me know if I calculated the right gains.

Please don't call µF mF, it's very confusing, mF really means 0.001F.

Use µF for values <99,999µF and F for values >0.1F.

If you can't write µ for whatever reason use u.

Erricgibbs : If you look at the original posters attachment of the circuit he is trying to understand you will see hes labeled some of the components. That is what Hero999 is getting at.
