摘要

Method for generating a waveform substantially sinusoidal containing digital data encoded with one of the second value and the first value in the phase angle θ _n which are selected, the phase angle θ In phase angles lying outside of regions having a range of Δθ initiated from _n, to produce a waveform having an amplitude Y defined by a first function is Y = sinθ, data of the value of the first to produce a waveform having an amplitude Y defined by a function of the first in phase angle located inside of these areas having a range of Δθ starting from the phase angle θ _n to be encoded, and amplitude is defined by a second function different from the Y = sinθ in the phase angle is located on the inside of these areas having a range of Δθ associated with each phase angle θ _n to be encoded data of the value of the second and includes the generating the waveform having a Y.
