WebAug 13, 2004 · 1,294. just an easy idea: On your power supply side you need a resistor and a differential amp. to measure the current through the supply lines. On the µC side you connect a port pin to a transistor that will draw some current from the power lines. thats all for unidirectional communication. More complicated will be a AC/DC coupling.

WebNov 15, 2024 · : On average, the losses on the HVDC lines are roughly 3.5% per 1000 km, contrasted with 6.7% for comparable AC lines at similar voltage levels (Siemens 2024). HVDC lines also experience losses at the converter stations, which range between 0.6 and 1% of the power delivered. WebA communication channel refers either to a physical transmission medium such as a wire, or to a logical connection over a multiplexed medium such as a radio channel in telecommunications and computer networking. A channel is used for information transfer of, for example, a digital bit stream, from one or several senders to one or several receivers.
