Generally, these two units are not considered as being parts of the channel. In certain cases, however, they may be considered as pans of the message source and message sink, (74) . In information theory (75) to Shannon, the channel can be characterized by the set of conditional probabilities of occurrence of all the messages received at the message sink when a given message emanates from the message source.
