ABSTRACT:
A method for generating a substantially sinusoidal waveform containing encoded digital data having one of a first value and a second value at selected phase angles θncomprises generating the waveform having an amplitude Y defined by a first function at phase angles lying outside of regions having a range Δθ beginning at each phase angle θn, said first function being Y=sin θ; generating the waveform having an amplitude Y defined by the first function at phase angles lying inside the regions having a range of Δθ beginning at each phase angle θnwhere data of the first value is to be encoded; and generating the waveform having an amplitude Y defined by a second function at phase angles lying inside the regions having a range of Δθ associated with each phase angle θnwhere data of the second value is to be encoded, the second function being different from Y=sin θ.
