Question

What are the 4 methods to reduce a boolean expression?

Answer 1

Four ways to reduce Boolean expression are
1) Algebraic manipulation of Boolean expressions
2) Exercises
3)Karnaugh maps.
4) Tabular method of minimisation

Answer 2

Answer:

Karnaugh Maps technique

Variable Entered Mapping Technique

Quine McCluskey Method

Exercises

Step-by-step explanation:

• Karnaugh map technique:-

The K-map method of solving the logical expressions is referred to as the graphical technique of simplifying Boolean expressions. K-maps are also referred to as 2D truth tables as each K-map is nothing but a different format of representing the values present in a one-dimensional truth table.

• Variable entered mapping (VEM) technique:-

A variable entered map (VEM) is a Karnaugh map in which the size of the map is reduced by removing one or more of the variables from the specification of the map cell locations.

• Quine-McClusky method:-

Quine–McCluskey algorithm is a method used for minimization of Boolean functions. It is functionally identical to Karnaugh mapping, but the tabular form makes it more efficient for use in computer algorithms, and it also gives a deterministic way to check that the minimal form of a Boolean function has been reached. It is sometimes referred to as the tabulation method.
