What pops into my memory is the reference common in digital audio of
Shannon coding or limits.

Shannon, Claude Elwood (1916- )
Mathematician and pioneer of communication theory, born in Gaylord, MI. He
studied at Michigan and at the Massachusetts Institute of Technology, and
in 1938 published a seminal paper on the application of symbolic logic to
relay circuits, which helped transform circuit design from an art into a
science. He worked at Bell Telephone Labs (1941-72) in the area of
information theory, and wrote The Mathematical Theory of Communication
(1949) with Warren Weaver.
