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.
24 Απρ 2014 · 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 also provides an example of converting a logic circuit diagram into a truth table and a Boolean expression.
Definitions. Schematic: A drawing of interconnected gates. Net: Wires at the same voltage (electrically connected) Netlist: A list of all the devices and connections in a schematic. Fan-in: The # of inputs to a gate. Fan-out: The # of loads the gate drives. 4.
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.
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-
28 Αυγ 2014 · The outputs of all NAND gates are high if any of the inputs are low. The symbol is an AND gate with a small circle on the output. The small circle represents inversion. Activity: Draw a circuit that shows how the NAND gate would be drawn using ONLY the basic logic 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.
