📖 Physical Concept & Comprehensive Explanation

Logic gates are the basic building blocks of digital integrated circuits. Basic gates are AND, OR, and NOT. NAND and NOR are universal gates because any logic system can be constructed exclusively using either. XOR and XNOR facilitate arithmetic binary addition.
