【Abstract】 By comparing and analyzing the experimental data,this paper puts forward that power line has very low input impedance, and it attenuates and jams the signal greatly. Because all these characteristics are time-variable, it′s very hard to establish a precise mathematical model. However,by using proper technologies, low voltage power line carrier communication system can meet the requirement of application, and it fits very well for carrier-current systems.更多还原
