Abstract: Power Line Carrier (PLC) has been around longer than we think. For example, at the turn of the 20th century, a 500 Hz signal on the power line was used to control street lights in New York City. The transmitters and receivers were originally powered by a M-G (motor-generator) set with a tuning coil 3feet in diameter. As technology has progressed, so did the PLC equipment. There are still many PLC's transmitters and receivers in use today that use vacuum tubes or discrete transistor logic but they are replaced with state-of-the-art components such as digital signal processors and other VLSI components.
