General Treatment of the Problem of Coding [reproduced typescript]

Murray Hill, N. J. Bell Telephone Laboratories, Incorporated August 1, 1950. [1]-6 leaves. 10 7/8 x 8 3/8 inches. Reproduced typescript, stapled upper left. Dated in type on the last page. Near Fine. Wraps. [29289]

The "Report of Proceedings, Symposium on Information Theory" (London) first published this paper in Sept. 1950." The "Transactions of the IRE Professional Group on Information Theory" reprinted it in Volume: 1, Issue: 1, Feb. 1953, pages 102-104, Feb. 1953. We are not aware of offprints from either publication. Offered here is a reproduced typescript of the paper from Shannon's file predating the first publication. We have not compared it to the published papers.

Shannon defines a typical communication system as consisting of five elements: 1) an information source. 2) an encoding or transmitting element. 3) a channel on which the signal is transmitted from transmitter to receiver. 4) a receiving and decoding device that recovers the original message from the received signal. And 5) the destination of the information.

From the Abstract: "...The central problems to be considered are how one can measure the capacity of a channel for transmitting information; how this capacity depends on various parameters such as bandwidth, available transmitter power and type of noise; and what is the best encoding system for a given information source to utilize a channel most efficiently..."
