摘要 |
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 theta<SUB>n </SUB>comprises generating the waveform having an amplitude Y defined by a first function at phase angles lying outside of regions having a range Deltatheta beginning at each phase angle theta<SUB>n</SUB>, said first function being Y=sin theta; generating the waveform having an amplitude Y defined by the first function at phase angles lying inside the regions having a range of Deltatheta beginning at each phase angle theta<SUB>n </SUB>where 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 Deltatheta associated with each phase angle theta<SUB>n </SUB>where data of the second value is to be encoded, the second function being different from Y=sin theta.
