1953 S. Goldman Information Theory i. 4 We shall use the contractions decit for decimal digit and binit for binary digit.
1953 S. Goldman Information Theory i. 5 The author does not know who originated the term binit, but he first heard it used by Dr. E. W. Samson.
1953 S. Goldman Information Theory i. 7 The total amount of information necessary to locate the cow is thus 6 binits.
1959 Science CXXX. 956/3 It is conventional practice in information theory to use logarithms to the base 2 of the probabilities expressed in the form of the ‘odds’, for or against. The units are known as ‘binits’.
1963 N. Abramson Information Theory & Coding i. 7 It is important to make a distinction between the binit (binary digit) and the bit.
1963 N. Abramson Information Theory & Coding ii. 18 If the 0 s and 1 s are not equally probable, then the amount of information provided by a given binit will be either less than or greater than 1 bit, depending upon its probability.
1965 H. B. Newcombe in Math. in Biol. & Med. (Med. Res. Council) ii. 46 We have found logarithms to the base 2 especially convenient and have called these ‘binit weights’.
