WebTranscribed image text: Boole's/Shannon's Expansion Theorem provides a mechanism to decompose a Boolean function. The Theorem says that a Boolean expression 'f' of n Boolean variables (X1, X2, decomposed as 4) Xn) can be f(X1, X2, ..Xn) (X1 AND f(1, X2,))OR (X1' AND f(O, X2, Xn)) Convince yourself that this decomposition is correct. WebApr 21, 2010 · George Boole (1815–1864) was an English mathematician and a founder of the algebraic tradition in logic. He worked as a schoolmaster in England and from 1849 until his death as professor of mathematics at Queen’s University, Cork, Ireland. He revolutionized logic by applying methods from the then-emerging field of symbolic …

WebUsing the Rule of 0 and 1, Boole proceeded to easily prove his four main theorems: the Expansion Theorem, the Reduction Theorem, the Elimina-tion Theorem and the Solution Theorem. Armed with these theorems, Boole transformed the process of correct reasoning about classes into a routine me- WebMay 10, 2024 · Boole's expansion theorem, often referred to as the Shannon expansion or decomposition, is the identity: F = x ⋅ F x + x ′ ⋅ F x ′, where F is any Boolean function, x is a variable, x ′ is the complement of x, and F x and F x ′ are F with the argument x set equal to 1 and to 0 respectively. raised ranch kitchen renovation
