Term: transinformation content

Synonym2: transmitted information
[Admitted]
Synonym3: mutual information
[Admitted]
Symbol: T(x,y)
Definition: difference between the information content I(x) conveyed by the occurrence of an event x, and the conditional information content I(x|y) conveyed by the occurrence of the same event, given the occurrence of another event y

T(x,y)=I(x)I(x|y)

Note 1 to entry: The two events are particularly a message at the message source of a channel and a message at the message sink of the channel.

Note 2 to entry: The transinformation content can also be expressed as: T(x,y)=I(x)+I(y)I(x,y), where I(y) is the information content of the event y. From this follows that it is symmetric in x and y: T(x,y)=T(y,x).
