IEVref: 171-07-31 ID: Language: en Status: Standard Term: average transinformation rate Synonym1: Synonym2: Synonym3: Symbol: T* Definition: quotient of the character mean transinformation content T′ by the mean duration of a pair of input and output characters T* = T′/t(X,Y) where X = {x1, …, xn} is the set of input characters xi (i = 1, …, n), Y = {y1, …, ym} is the set of output characters yj (j = 1, …, m) and $t\left(X,Y\right)=\sum _{i=1}^{n}\sum _{j=1}^{m}p\left({x}_{i},{y}_{j}\right)\cdot t\left({x}_{i},{y}_{j}\right)$ is the mean value of the duration t(xi,yj) of the pair of characters (xi,yj) which occurs with joint probability p(xi,yj).Note 1 to entry: The average transinformation rate can be expressed in a unit such as the shannon per character and second.
