The impedance of the winding consists of one or several turns of a control cable run through the ferrite ring and is too low both for low-frequency operating signals and for commercial frequency alternating current At the same time it is too high for high-frequency (short pulse) signals within the selected frequency range which depends on the number of turns, material and size of the ring itself.
