Cosa (chi) è Z-channel (information theory) - definizione

COMMUNICATIONS CHANNEL USED IN CODING THEORY AND INFORMATION THEORY
Z Channel (information theory)
  • The Z-channel sees each 0 bit of a message transmitted correctly always and each 1 bit transmitted correctly with probability 1–''p'', due to noise across the transmission medium.

Z-channel (information theory)         
In coding theory and information theory, a Z-channel (binary asymmetric channel) is a communications channel used to model the behaviour of some data storage systems.
Information theory         
  • ''H''<sub>b</sub>(''p'')}}.  The entropy is maximized at 1 bit per trial when the two possible outcomes are equally probable, as in an unbiased coin toss.
  • A picture showing scratches on the readable surface of a CD-R.  Music and data CDs are coded using error correcting codes and thus can still be read even if they have minor scratches using [[error detection and correction]].

Information theory is the scientific study of the quantification, storage, and communication of digital information. The field was fundamentally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s.
