Claim:
1. A power supply system to generate a power signal for providing power to a device, the power supply system comprising: a transmitter to: wherein the transmitter is to modulate the data signal and the single-state binary control signal to occupy different modulation states of a plurality of modulation states provided on the power signal, the plurality of modulation states being a plurality of phase angles of a phase-shift keying modulation of the power signal, the transmitter is to modulate the single-state binary control signal on a phase angle of the plurality of phase angles different from a phase angle of the plurality of phase angles on which the transmitter modulates the data signal, the device includes a phase-locked loop to generate a sinusoidal wave to demodulate the data signal and the binary control signal, and the single-state binary control signal and each bit of the stream of bits of the data signal are encoded according to a same unit of time, the unit of time being a fixed multiple of a quarter-period of the sinusoidal wave.
