ABSTRACT:
An impedance measurement system rapidly determines impedance of a sinusoidal signal at a known frequency. The sinusoidal signal can represent a forward voltage, a reflected voltage, a voltage, or a current on a transmission line. The impedance calculation is made by receiving two samples of a signal representing forward voltage and reflected voltage or two samples each of current and voltage. The samples are used to determine an amplitude value and a phase value for the signal. The amplitude and phase value are utilized to calculate the impedance.
