**Reduction of Logic Equations using Karnaugh Maps**

• A Karnaugh map is a graphical method for representing and simplifying Boolean expressions • “Don’t care” entries in a K-map can take values of 1 or 0 depending... A function can be more systematically simplified by Karnaugh Map. Two variables. Consider Example A above: This is the logic behind the combination of neighboring squares in the Karnaugh map: Three variables . Example B above has 3 variables: and the corresponding truth table is Either of the two Karnaugh maps can be used: The function can be represented by the OR of the three resulting terms

The same method applies to larger K maps of 4, 5, and 6 variables. Four variable K maps have sixteen cells, since 2 to the 4th is 16. Five variable K maps are mapped as two, sixteen cell maps side by side. It is like mapping one map above the other, with the same numbered cells being redundant. Six variable K maps result in four, sixteen cell maps together in a square pattern. Top to bottom... 4-Variable Karnaugh Map Tutorial In this tutorial, we will look at solving a four variable Karnaugh Map. The four-variable Karnaugh Map will have 16 cells, but other than that, the procedure is pretty much the same as was discussed in the three-variable example.

- The logical OR function of two variables is represented mathematically by a + between the two variables, for example, A + B. Addition in Boolean algebra involves variables whose …
- Ex. Convert the Boolean function F = x + y z into a sum of minterms by using a truth table. Solution: First, we derive the truth table 3.10, then from the table we get F = 1 for minterms m 3 , m 4 …
- The K-map looks the same except we circle 0's rather than 1's: Also notice how the expressions are formed for each prime implicant. If the index for the variable is a 1 the variable …
