  • SINGLE AND MULTIPLE SINEWAVE MODULATION AND DEMODULATION TECHNIQUES EMPLOYING CARRIER-ZERO AND CARRIER-PEAK DATA-WORD START AND STOP
    Publication number: 20070274415
    Abstract: A method for detecting encoded digital data from a substantially sinusoidal waveform, the encoded digital data having one of a first value and a second value at selected phase angles ?n comprises generating the waveform having an amplitude Y defined by a first function at phase angles lying outside of regions having a range ?? beginning at each phase angle ?n, said first function being Y=sin ?; generating the waveform having an amplitude Y defined by the first function at phase angles lying inside the regions having a range of ?? beginning at each phase angle ?n 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 ?? associated with each phase angle ?n where data of the second value is to be encoded, the second function being different from Y=sin ?, the detection including deriving sync pulses from minima and maxima of the substantially sinusoidal waveform to frame data words.
    Type: Application
