    Answer to my question by skogsgurra

    Sorry, for opening a new thread. I am using this forum for the first time. Just after having submitted the new thread I realized that I did wrong. I surely know that one can make complex impedances from real components. My only problem was to tell mathcad not to use complex fitting values...

    Answer to my question by skogsgurra

    Hi Skogsgurra your answer does not really help. Of course I do know that impedances are normally complex. But assume I am calculating the complex impedance of an RC-circuit. The parameters of R and C will be real. If I then use the complex impedance of the RC-circuit thus obtained as "data"...

    Fitting complex functions with real fitting parameters

    Hi All: I have a problem which should be easy to solve, however I cannot manage to do it. I am trying for the first time to fit complex impedance data with equivalent circuits using mathcad programs like Complex_Fit.mcd, or Least_Squared_Error.mcd. The fitting procedure itself works, however I...
