  • Signaling system
    Patent number: 4866771
    Abstract: Periodic components of a data signal are generated from a periodic original signal in a manner to cause the periodic components to represent not only the data but also information about characteristics of the original signal; subsequently both the data and the information about the original signal characteristics are derived from the periodic components. The periodic components of a data signal are generated at frequencies within a frequency band and in a manner such that the components precisely define a fixed frequency outside the spectral band.
