How to syntetize a circuit from its transfer function???

[Leron]

Hi guys!
I have a problem... as stated in the subject I have the trasfer function of a certain passive circuit, in the form of a padè approximation obtained by measurements fitting and I would like to find an appropriate lumped circuit to implement this function.
Do you yuou know which tool can I use (something like a matlab routine or some free software) or where to find good references for this???
Thank you as usual for your attention

Post the transfer function, or the transfer waveform, maybe we can help by looking it.

amplitude approximations

Some filter programs allow you to enter the amplitude points and it will synthesize the filter to match. Some circuit analysis programs with optimizers will adjust the filter part values to match your graphical input.
