Part 1 - Fundamentals of Power Line Data Transmission
In the first part of the article, we briefly familiarized ourselves with the basic concepts of data transmission over power lines. We learned what a “useful signal” is, how it can be used to encode the transmitted information. But there was not a word about how this device should be made physically, how it would generate a signal, and how it would generally be connected to a 220 V.
In this and the next parts of the article, we will describe what basic blocks should be in the simplest PLC data transmission device . Gradually, as a constructor, we will add block by block to the overall picture and figure out what each block is for and how it works.
