Abstract
A method and apparatus for encoding information symbols onto an analog host signal modifies signal peaks of the host signal to fall within predetermined amplitude bands. A set of symbols is defined wherein each symbol corresponds to a defined number of signal peaks or to a particular value of signal peak within a band. An additional information channel may be created by altering polarity changes of signal peaks in accordance with predetermined polarity sequences to represent a second set of defined symbols.
