"SHANNON, CLAUDE E.
Memory Requirements in a Telephone Exchange (Manuscript Received Dec. 7, 1949).
(New York), American Telephone and Telegraph Company, 1950. 8vo. In the original printed blue wrappers. In Volume XXIX, July, No. 3, 1950 of ""The Bell System Technical Journal"". A bit of minor marginal browning to extremities, otherwise fine and clean. Pp. 343-359. [Entire issue: Pp. 295-468].
Reference : 62913
First edition of Shannon's influential paper on how to construct a telephone exchange network. ""The problem of designing a good rearrangeable network was (probably first) considered in a paper of C. E. Shannon investigating memory requirements in a telephone exchange. On the networks that he considered he imposed the realistic ""separate memory condition"" to the effect that in operation a separate part of the memory can be signed to each call on progress. This means that completion of a new call or termination of an old call will not disturb the state of memory elements associated with any call in progress. [...] Shannon's separate memory condition is actually met by modern connecting networks [...]. (Benes, Vaclav Edward. Mathematical Theory of Connecting Networks and Telephone Traffic: 017, 1965, p. 119.) Claude Shannon is widely regarded as being the father of information theory and cryptography. Origins of Cyberspace 883.The present issue also includes:1. Southworth, George C. Principles and Applications of Waveguide Transmission. Pp. 295-342.2. Hartley, R.V.L. Matter, A Mode of Motion. Pp. 350-368.3. Hartley, R.V.L. The Reflection of Diverging Waves by a Gyrostatic Medium. Pp. 369-389.4. Pierce, J.R. Traveling-Wave Tubes (Third Installment). Pp. 390-460.
