4o. Black cloth.
In an effort to improve the speed of data transmission over telegraph wires, Nyquist isolated two key factors -- signal shaping and choice of codes. "The first is concerned with the best shape to be impressed on the transmitting medium so as to permit of greater speed without undue interference either in the circuit under consideration or in those adjacent, while the latter deals with the choice of codes which will permit of transmitting a maximum amount of intelligence with a given number signal elements" (p. 324). In his 1948 paper, "A mathematical theory of communication" Claude Shannon credited Nyquist's paper as being one of the foundations of information theory. OOC 343.
