چکیده مقاله:

Analog PLC systems are used in electrical installations to communicate for the purposes of remote protection, sending and receiving data, fax or telephone conversations, which are generally used in high-voltage power transmission lines. The modulation arrangement that is used for this type of system is the SSB range modulation, in which one or more telephone channels are transmitted on a carrier signal, and the frequency range of this carrier signal is from ۲۰ kHz to ۵۰۰ kHz, and sometimes up to ۱ MHz. increases. In this article, the function of PLC and the mode of coupling are examined and then the place of modulation is examined and analyzed.
