Hi all ,
i searched the forum , but didnt find an answer. i have a circuit with a capacitor and an resistor in parallel and then a capacitor and a resistor in series.
(see enclosed picture). I want to create a state space model for this circuit. I used the mesh and node rule to replace the capacitor voltages by their first order derivative. My problem is that in the final equotation there is a second order deviation and i have no idea how to get rid of the second order.
sorry , that the picture is head ups, can i change that ?

Have a nice evening
