http://users.cms.caltech.edu/~hou/papers/MMS-Intrawave-2014.pdf WebModulation is the addition of information to an electronic or optical carrier signal. A carrier signal is one with a steady waveform -- constant height (amplitude) and frequency. Information can be added to the carrier by varying its amplitude , frequency , phase , polarization (for optical signals), and even quantum-level phenomena like spin .
