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( X,Y )= i=1 n j=1 m p( x i , y j )t( x i , y j ) MathType@MTEF@5@5@+= feaagKart1ev2aqatCvAUfeBSjuyZL2yd9gzLbvyNv2CaerbbjxAHX garuavP1wzZbItLDhis9wBH5garmWu51MyVXgaruWqVvNCPvMCG4uz 3bqee0evGueE0jxyaibaiGc9aspC0FXdbbc9asFfpec8Eeeu0lXdbb a9frFj0xb9Lqpepeea0xd9s8qiYRWxGi6xij=hbba9q8aq0=yq=He9 q8qiLsFr0=vr0=vr0db8meaabaGacmaadiWaaiWabaabaiaafaaake aacaWG0bWaaeWaaeaacaWGybGaaiilaiaadMfaaiaawIcacaGLPaaa cqGH9aqpdaaeWbqaamaaqahabaGaamiCaiaacIcacaWG4bWaaSbaaS qaaiaadMgaaeqaaOGaaiilaiaadMhadaWgaaWcbaGaamOAaaqabaGc caGGPaGaeyyXICTaamiDaiaacIcacaWG4bWaaSbaaSqaaiaadMgaae qaaOGaaiilaiaadMhadaWgaaWcbaGaamOAaaqabaGccaGGPaaaleaa caWGQbGaeyypa0JaaGymaaqaaiaad2gaa0GaeyyeIuoaaSqaaiaadM gacqGH9aqpcaaIXaaabaGaamOBaaqdcqGHris5aaaa@5F94@ 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.
