Ali,

Try the attached  Excel file for a simple example. 

You may be able to re-write the equations for your LoPass.

For more complex circuits, such as AFX-3RLFADI.html

I depend on SPICE  at  PartSim.com (link below) . 

Spice answers many questions about sequential circuit interactions

especially when impedance variations are shifting resonant frequencies.

Hi Ali,

Maybe this link be useful for you

All of the operations that you want could be calculated with this toolbar, but I think it doesn't work with Excel 2013.
