Self-clocking signal


In telecommunications and electronics, a self-clocking signal is one that can be decoded without need for a separate clock signal or other source of synchronization. This is usually done by including embedded Self-clocking signal synchronization information within the signal, and adding constraints on the coding of the data payload such that false synchronization can easily be detected.


Examples of self-clocking signals include:


Isochronous:



  • Manchester code. The clock signals occur at the transition points.
  • PDH signals

Anisochronous:



  • Morse code
  • Asynchronous start-stop


 


Electronics Topics

The field of electronics is the study and use of systems that operate by controlling the flow of electrons or other electrically charged particles in devices such as thermionic valves and semiconductors. The design and construction of electronic circuits to solve practical problems is part of the fields of electronic engineering, and the hardware design side of computer engineering. The study of new semiconductor devices and their technology is sometimes considered as a branch of physics.
