CALIBRATION OF IMPEDANCES BY THE SUBSTITUTION METHOD: NUMERICAL UNCERTAINTY EVALUATION |

| Luca Callegaro, Walter Bich |
- Abstract:
- Several theoretical and practical difficulties affect the analytical evaluation of uncertainty of measurements dealing with complex variables. Computerintensive methods based on bootstrap and Monte Carlo techniques are here employed to investigate the uncertainty evaluation of a basic measurement procedure, the calibration of an impedance standard with the substitution method, using an RLC automatic bridge as a comparator. A procedure giving confidence intervals for the impedance parameter is shown in principle; results of calculations made with an implementation on actual measurement data are shown.
