26 Νοε 2016 · This document discusses digital logic gates and circuits. It describes the basic logic gates - NOT, AND, OR, NAND, NOR, XOR, XNOR - and how each is represented by a truth table.
30 Απρ 2018 · This document discusses Boolean algebra and logic gates. It begins by defining basic logic gates like AND, OR, NOT, NAND, NOR, and XOR. It then provides truth tables and circuit diagrams for each gate.
24 Απρ 2014 · This document discusses various logic gates and their truth tables. It begins by explaining the AND, OR, and NOT gates and providing their respective logic symbols, descriptions, and truth tables. It then covers the NAND, NOR, XOR, and XNOR gates.
28 Αυγ 2014 · Presentation Transcript. LOGIC GATES. INTRODUCTION TO LOGIC GATES • Boolean functions may be practically implemented by using electronic gates. The following points are important to understand. • Electronic gates require a power supply.
3 Universal Set of Gates: Motivation AND, OR, NOT: Logic gates related to reasoning from Aristotle ( BCE). NAND, NOR: Inverted AND, Inverted OR gates. For VLSI technologies, all gates are inverted (AND,OR operation with a bubble at output). XOR: Exclusive OR gates. Parity check.
Logic gates are circuits that implement the logical AND, OR, NOT and other boolean functions, whose truth tables we studied last week. There are many ways to implement logic gates using transistors, but the most common is known as comple-mentary metal{oxide{semiconductor, or CMOS, which uses pMOS and nMOS transistors in a complemen-tary manner.
