IMPEDANCE BODE PLOT VS EQUIVALENT CIRCUIT

Dear all, I'm looking for support about the following question: If I have an Impedance bode plot, is there a method to extract the equivalent circuit? Thinking about RC ladder network or RL ladder network? Thanks Regards

You are describing circuit synthesis. For a good introduction, see: Chen, W-K. Passive and Active Filters: Theory and Implementation, Wiley 1986, ISBN 0-471-82352-X.

Thanks. Assuming a Laplace plot as input parameter, do you know if matlab has some built in functions to do that?

My pleasure.

It does not. I cannot find any File Exchange contributions that do that, or even do the necessary vector continued fraction expansion necessary to calculate the component values from the Laplace transfer function. You would have to write your own using the deconv function. I cannot find any books that appear to implement this in MATLAB.
