Ralph Hartley's 1928 paper, Transmission of Information, takes advantage of the phrase information as a measurable quantity, reflecting the receiver's means to distinguish just one sequence of symbols from every other, Consequently quantifying information as H = log Sn database = n log S, wherever S was the quantity of doable symbols, and n the quantity of symbols inside of a transmission. The device of information was therefore the decimal digit, which due to the fact has sometimes been called the hartley in his honor as a device or scale or measure of information. Alan Turing in 1940 applied related Thoughts as Portion of the statistical Assessment from the breaking on the German next world war Enigma ciphers.[citation necessary]
