Brit.

/ˈʃanən/, U.S.

/ˈʃænən/

Etymology: < the name of Claude Elwood Shannon (1916–2001), U.S. mathematician.

Information Theory.

Used attributively and in the possessive to designate various concepts arising from Claude Shannon's work, esp. Shannon's (second or capacity) theorem, a theorem regarding the ability of a noisy channel to carry information with no more than an arbitrarily small frequency of errors (see quot. 1970).
