SLiCAP GPZ estimator


Notes for SLiCAP Gain Pole Zero estimator V0.1
    • Please upload an ASCII file with measurement or simulation data. The first line is ignored, the following lines must have three numbers per line: FREQUENCY, REAL_PART, IMAGINARY_PART. Scientific notation with decimal point shoud be used.

      Example data file:
      freqency real___ imag_____ * the first line will be ignored
      1.000E02 10.0E03 0.10E-06
      5.000E02 10.0E03 -0.20E-06
      ....... ........ ......... * etcetera


      The number of data lines must be larger than the sum of the number of poles and zeros plus one.



    • Please upload an ASCII file with model data (gain, poles and zeros with start values) and fit range (frequency).

      Example model file:
      fstart 10.00 * Start frequency for the estimator
      fstop 10E6 * Stop frequency for the estimator
      g 10E3 * start value for the gain
      p -10.0 0.0 * start value for a real pole
      p -1.0E06 5.0E06 * start value for a complex pole pair, SLiCAP will add complex conjugate!
      z -8.0E06 0.0 * start value for a real zero
      z 1.0E08 3.0E09 * start value for a complex zero pair, SLiCAP will add complex conjugate!
      . ...... ...... * etcetera


      The identifiers 'fstop', 'fstart', 'g', 'p' and 'z' are not case sensitive. Lines that do not start with one of these identifiers are ignored!
