Module #4: Logic Minimization The laws of Boolean algebra generally hold for XOR functions as well, except that DeMorganвЂ™s law takes a different form. Recall from the pervious module that the XOR function output is asserted whenever an odd number of inputs are asserted, and that the XNOR function output is asserted https://en.wikipedia.org/wiki/Elementary_Boolean_algebra Boolean Algebra. Boolean Algebra is a way of formally specifying, or describing, a particular situation or procedure. We use variables to represent elements of our situation or procedure. Variables may take one of only two values. Traditionally this would be True and False..

In Boolean algebra, circuit minimization is the problem of obtaining the smallest logic circuit (Boolean formula) that represents a given Boolean function or truth table. For the case when the boolean function is specified by a circuit (that is, we want to find an equivalent circuit of minimum size possible), the unbounded circuit minimization problem was long-conjectured to be -complete, a Boolean algebra finds its most practical use in the simplification of logic circuits. If we translate a logic circuitвЂ™s function into symbolic (Boolean) form, and apply certain algebraic rules to the resulting equation to reduce the number of terms and/or arithmetic operations, the simplified equation may be translated back into circuit form for a logic circuit performing the same function
