Data communication over power supply lines of an electronic system

摘要

Disclosed are various embodiments for communicating information between various electronic components. A local device may comprise a transmitter to convert communication signals into modulated signals. Modulated signals are injected into a shared power supply line. The remote device may comprise a receiver for identifying the injected signal, demodulating the injected signal, and processing the demodulated signal.
