摘要 |
<p>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 thetan 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 thetan, said first function being Y = sintheta; generating the waveform having an amplitude Y defined by the first functional phase angles lying inside the regions having a range of Deltatheta beginning at each phase angle thetan 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 thetan where data of the second value is to be encoded, the second function being different from Y=sintheta.</p> |
