Abstract :
The introduced measuring system determines low impedances by comparing the current and voltage values of two impedances. The voltages are measured by digital voltage compensators. The currents are determined by compensating the magnetic field of two currents in a magnetic coil. Digital signal synthesis is used for the coherent sources.
