Nov 26, 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.
Apr 30, 2018 · 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.
Dec 26, 2013 · This document discusses logic gates and their functions. It describes three basic logic gates: AND gates, OR gates, and NOT gates. AND gates only output true if both inputs are true. OR gates output true if either input is true. NOT gates reverse the input logic state. Examples are given for each gate type.
Aug 28, 2014 · 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. Slideshow 3648136 by keren
A logic gate is a decision- making building block which has one output and two or more inputs as shown in Figure 1. 2. The input and output signals of a gate can have either of two values, binary 1 or 0. The value of the output of a gate is decided by the values of its inputs.
Logic Gates. Basic logic circuits with one or more inputs and one output are known as gates. • Gates are used as the building blocks in the design of more complex digital logic circuits. Representing Logic Functions. There are several ways of representing logic functions: Symbols to represent the gates. Truth tables. Boolean algebra.
A logic gate is a simple electric circuit consisting of two inputs and a single output. The most frequent names for logic gates are AND, OR, NOT, XOR (Exclusive or), NAND (NOT AND), and NOR. An OR logic gate begins with the provision of two electrical inputs.
Types of Logic Gates! • Major logic gates: NOT, AND, OR, and XOR • There are also other ones, such as NAND, NOR, and XNOR that we’re not going to cover. • This is called Boolean logic • In a circuit schematic each logic gate is represented by a different picture, like the ones shown below.
Apr 24, 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.
The document discusses the history and development of logic gates from diode-resistor logic to modern CMOS integrated circuits. It provides examples of common logic gates like AND, OR, NOT, NAND and XOR gates and explains their truth tables and schematic symbols.
