Abstract

This paper presents a new digital algorithm for measuring an unknown impedance. The proposed algorithm is based on the minimization of the least absolute value of the error. The algorithm developed in [5] is used to solve the resulting optimization problem. The proposed algorithm is general enough to implement for measuring impedance. The effects of critical parameters on the accuracy of the measured unknown impedance are discussed. Results from simulated data are given to form our conclusions.
