Abstract
The present application discloses an identification circuit for a power-line carrier signal. During signal transmission on a power line, the amplitude change and duration of a voltage signal on the power line are identified and then decoded into corresponding data, so as to reduce dependency on a power supply voltage during signal identification, and prevent the signal identification rate from decreasing as a result of an increase in the transmission distance, thereby reducing requirements for a system power supply.
