Can Simscape Electronics give the transfer function of a filter in closed form solution?

For a linear system such as an op amp active filter can simscape electronics give me the transfer function as an s-domain equation (laplace domain - steady state)?

If you have a set of input/output Simulink signals that you can designate, you can use Simulink Control Design to linearize the electrical filter model.

Sebastian, thanks for the answer. Can you be more specific about the equations/closed-form-solution? I do not want a numerical solution, I want the equation for the transfer function in the form of a Laplace transform of the differential equations assuming that the equations would be linear ordinary differential equations. An ideal op amp circuit would be inherently linear so I do not think any linearization would be necessary.

Right. If you linearize an already-linear system, then this process basically converts the model into a state-space or transfer function representation. So that would be how you extract the s-domain transfer function from a Simulink model.
