There are hybrid transformers in the central office and in the telephone. In the telephone 2 wires from the transmitter and 2 wires from the receiver are fed into a transformer that gives a two-wire output to the line. At the central office, where separate transmit and receive paths must be established, the reverse happens. The real art of telephony lies in the balancing of these transmission paths. However, for that course, we charge. Ciao, Vic
