Cox – Spring 2010 The University Of Alabama in Hunt sville Computer Science Boolean Algebra The algebraic system usually used to work with binary logic expressions Postulates: 1. Closure: Any defined operation on (0, 1) gives (0,1) 2. Identity: 0 + x = x ; 1 x = x 3. Commutative: x + y = y + x ; xy ...
CHAPTER 3 Boolean Algebra and Digital Logic
www2.southeastern.edu3.3 Logic Gates 147 We see that Boolean functions are implemented in digital computer circuits called gates. A gate is an electronic device that produces a result based on two or more input values. o In reality, gates consist of one to six transistors, but digital designers think of …

Simplification of Boolean functions
homepage.cs.uiowa.eduSimplification of Boolean functions Using the theorems of Boolean Algebra, the algebraic forms of functions can often be simplified, which leads to simpler (and cheaper) implementations. Example 1 F = A.B + A.B + B.C = A. (B + B) + B.C How many gates do you save = A.1 + B.C from this simplification? = A + B.C A A B F B F C C

Otherwise 0. An OR gate is a logic circuit that performs an OR operation on the circuit's input.
