SYSTEM AND METHOD FOR POWER LINE CARRIER COMMUNICATION USING HIGH FREQUENCY TONE BURSTS

摘要

A communication system and method is utilized to communicate data over an AC power line. Tone burst are superimposed on an AC power signal at predetermined voltage reference levels or at predetermined phase angles to represent bit values. These bit values are represented by either the presence or the absence of the tone burst on the AC power signal. In this manner, control information can be communicated to an apparatus, such as a ballast for a gas discharge lamp.
