Abstract

A digital method for the measurement of the real and imaginary parts of the impedance (rectangular-form), as well as its magnitude and phase (polar-form) is described. It depends on using a novel hybrid processor that gives digital numbers that are proportional to the imaginary and real parts of the impedance, besides the magnitude and phase. A circuit for indicating whether the impedance is capacitive or inductive is also given. This method could also be used for admittance measurement and for the determination of the inductance or capacitance of any circuit. The basic accuracy of the system is about 0.2%
