3
Review of Last Lecture DeMorag Theorem Introduction to simulation of digital circuits Simulation of AND, OR, NOT, Ex-OR, NAND gates

4
Simplification using Boolean Algebra In the application of Boolean algebra, we have to reduce a particular expression to its simplest form and then use the simplified expression to implement our digital circuit. For Example: Simplify the following expression. AB + A(B + C) + B (B + C)
