Abstract
An electrical information transmitting means for consumer load control comprises a transmitter which transmits a coded signal through the conductors of an alternating current electrical distribution network as a sequence of wave-form distortions to a receiver which decodes the signal. The receiver comprises two correlators connected in quadrature, and the transmitters and each correlator synthesize synchronous signals from the power frequency, all of which is locked thereto. The D.C. voltage outputs of the correlators are squared and summed so that the receiver is independent of phase angle.
