Minimization and karnaugh maps, C/C++ Programming

Assignment Help:

There are formal ways of reducing Boolean expressions in order to minimize the logic circuit. The two elementary ways of minimization are using Boolean expressions/De Morgan Theorem (math's approach) or Karnaugh maps (Graphical approach). The first is simply a set of mathematical rules, which help us eliminate redundant terms in out expression. Let us have a closer look. The simplest Identities are shown below:
 
            A +1 = 1
            A .1 = A
            A .A = A
            A +A = A
            /A + A =1
            /A . A = 0
 
These are common sense since from the OR truth table we can see that if B is always 1 then the output is the same always 1.

Hence if in an expression we see A+1 we can replace 1. The same applies to the remaining identities.
