“H, the information of the message, as the logarithm of the number of possible sequences of symbols which might have been selected and showed that H = n log s Here n is the number of symbols selected, and s is the number of different symbols in the set from which symbols are selected. This is acceptable in the light of our present knowledge of information theory only if successive symbols are chosen independently and if any of the s symbols is equally likely to be selected. In this case, we need merely note, as before, that the logarithm of s, the number of symbols, is the number of independent 0-or-1 choices that can be represented or sent simultaneously, and it is reasonable that the rate of transmission of information should be the rate of sending symbols per second n, times the number of independent 0-or-1 choices that can be conveyed per symbol.
