摘要:
Digital data is transmitted over AC power lines at typically a 300 baud rate and at a frequency of 130 kilohertz representing a binary ONE and 131 kilohertz representing a binary ZERO. Apparatus in the receiver relay including a quadrature detector converts the high frequency signals to digital binary signals which are applied to a microprocessor. The microprocessor generates signals to control relays in accordance with the information received from the AC power lines.
