Logic Gates Explained: Basic, Universal & Exclusive Gates with Applications | Digital Electronics

Описание: Welcome to Lecture 9 of the Digital Electronics Course!

In this session, we cover one of the most essential concepts in digital logic—Logic Gates. You'll explore Basic Gates (AND, OR, NOT), Universal Gates (NAND, NOR), and Exclusive Gates (XOR, XNOR) with truth tables, symbols, Boolean expressions, and real-world applications.

Whether you're a beginner or revising for an exam, this lecture builds the foundation of digital circuit design and analysis.

🔍 Topics Covered:
✅ Basic Logic Gates – AND, OR, NOT
✅ Universal Gates – NAND, NOR (with gate implementations)
✅ Exclusive Gates – XOR, XNOR (with key differences from OR)
✅ Logic Symbols, Truth Tables & Boolean Expressions
✅ Applications in Adder Circuits, Parity Checkers, and more
✅ Practice:
• Converting Logic Diagrams to Boolean Expressions
• Designing Circuits from Boolean Expressions
• Identifying Unknown Gates via Behavior/Truth Table

This lecture includes clear examples, circuit diagrams, and exam-focused practice problems.
