An optimisation process has calculated impedance values (R + jX) at differ= ent=20 frequencies Now I need to find *one* RLC network that represents all these impedances= at=20 those frequencies. Solving this manually is quite cumbersome Is there a (free) software around that solves that?=20 A web search did not reveal anything Any other ideas? Jurgen Bartels Suellwarden, N. Germany hor.
