How does a hybrid in telephone networks work?

The circuit operation is as follows:

The input signal is coupled to the B and F windings similarly. By the C winding, the input is coupled to the 2-wire circuit. Similar signal when this flows through the balanced 2-wire couples the signal to winding D by winding C. The signal induced in B flows by E and induces a current in D that opposes the current induced through F. If the impedance ZB closely matches that of the 2-wire circuit, the consequence of input signal on the output winding D is fully nullified. In a same way, the input signal from the subscriber end is fully nullified from coupling in the winding A.
