ABSTRACT:
A receiver of pulsed phase modulated signals is disclosed. These signals are produced by switching a reactance on and off a power line. The receiver produces a sinusoidal current in phase with the current on the power line and a sinusoidal voltage nominally 90 degrees out of phase with the voltage on the power line. These sinusoids are multiplied together to produce a sinusoid of double the original frequency (which may be filtered out) and voltage levels (positive when the reactance is on line and negative when it is off). The absolute value difference between these voltage levels (if any) is used as an error voltage for feedback. The voltage sinusoid is modified by this feedback.
