📘Unit 3- Boolean Algebra and Karnaugh Map
Boolean Algebra is a system of mathematics used to represent and simplify logical operations. Digital circuits and microprocessors use Boolean rules to make decisions based on binary values, 0 and 1.
In this lesson, students learn how logical expressions are formed using operators like AND, OR, and NOT. The chapter explains the basic Boolean laws and theorems that help reduce long expressions into simpler forms. Simplifying expressions makes digital circuits smaller, faster, and more efficient.
The lesson also introduces the Karnaugh Map (K-map), a simple visual method for minimizing Boolean expressions. Students learn how to fill the K-map from a truth table, group adjacent 1s, and write the simplest possible expression. K-maps help avoid mistakes and reduce the number of logic gates required to build a circuit.
This chapter strengthens the understanding of digital logic and shows how mathematical simplification leads to better circuit design.
