چکیده:

Technology of data transfer system through power lines is a system for data transferring through a conductor that is used for electric energy transferring too. For connect the communication system to power system coupling capacitors and line matching unites should be used. For giving way to data current should be used line traps. Modulation and coding are actions those are done for availability to trust worthy and effective connection. Amplitude modulator because of need to less band width, use of simple detector system , having simple circuit and ability of separating carrier signal from external signal without need to filter is suitable for the use in PLC system
