Abstract :
A new method is described for measuring an impedance accessible only through an unknown 2-port linear system. Four calibrating impedances are used: a known resistance, a short circuit and two other unknown reactances. The value of impedance is calculable directly from the input measurements using simple step-by-step formulas.
