Logic Gates - Digital Electronics Basics (AND, OR, NOT, etc.) | TechAmbitionX | Notes By Mr. BILRED Logic Gates Definition: Logic gates are the basic building blocks of digital electronics. They take one or more binary inputs (0 = LOW / FALSE, 1 = HIGH / TRUE) and give a single output, based on simple logic rules. Key Idea: They work using Boolean Algebra , where: AND → Multiplication (·) OR → Addition (+) NOT → Complement (′) Types of Basic Logic Gates 1. AND Gate Definition: Output is 1 only when all inputs are 1. Formula: Y = A · B Example IC: 7408 (Quad 2-input AND gate) A B Output (A·B) 0 0 0 0 1 0 1 0 0 1 1 1 2. OR Gate Definition: Output is 1 if any input is 1. Formula: Y = A + B Example IC: 7432 (Quad 2-input OR gate) A B Output (A + B) 0 0 0 0 1 1 1 0 1 1 1 1 3. NOT Gate (Inverter) Definition: ...
