Nov 9, 2020 at 7:05 | comment | added | Verbal Kint | Yes, these FACTs are an amazingly powerful technique to deal with these types of structures. As you can see, I compare the FACTs response with that of the brute-force series-parallel arrangement and they are identical. For the sake of further verification, I run a quick SPICE sim and yes, the impedance peaks nearly 60 dBohms which is close to 1 kohms as indicated. Unless I used wrong components values in my sim and example? | |
Nov 9, 2020 at 6:05 | comment | added | jrive | this approach is very interesting and new to me. I will look at the links you provided. Are you sure about the impedance, though? I get closer to 50 when using complex math....in fact, I get 68ohms! | |

Minor typo in one of the formulas.

Updated the Mathcad plot to highlight the resonant frequency
