Which gate is equivalent to NOR or XOR?

Which gate is equivalent to NOR or XOR?

XNOR gate
The XNOR gate (also known as a XORN’T, ENOR, EXNOR or NXOR) – and pronounced as Exclusive NOR – is a digital logic gate whose function is the logical complement of the exclusive OR gate (XOR gate). Logically, an XNOR gate is a NOT gate followed by an XOR gate.

Which gate is equivalent to AND gate?

An AND gate is equivalent to an inverted-input NOR gate. II. An OR gate is equivalent to an inverted-input NAND gate.

What is XOR logic gates?

“XOR” an abbreviation for “Exclusively-OR.” The simplest XOR gate is a two-input digital circuit that outputs a logical “1” if the two input values differ, i.e., its output is a logical “1” if either of its inputs are 1, but not at the same time (exclusively). The symbol and truth table for an XOR is shown in Figure 1.

What is a NAND gate equivalent to?

A NAND gate is equivalent to an inverted-input OR gate. Page 5. An AND gate is equivalent to an inverted-input NOR gate. A NOR gate is equivalent to an inverted-input AND gate.

Which is fastest logic family?

Emitter-coupled logic (ECL)
Emitter-coupled logic (ECL) is a BJT-based logic family which is generally considered as the fastest logic available. ECL achieves its high-speed operation by employing a relatively small voltage swing and preventing the transistors from entering the saturation region.

Is XOR a universal gate?

You can’t derive an OR (or AND, NOR, NAND) gate from only XOR (or XNOR) gates, because they are not universal gates. Here is an argument against XOR and XNOR as universal gates. An XOR gate is a parity generator.

What is the difference between OR AND XOR?

As nouns the difference between or and xor. is that or is (tincture) the gold or yellow tincture on a coat of arms while xor is the logic function exclusive or (as opposed to inclusive or), whose output is true only when exactly one of its inputs is true.

What does a XOR gate do?

XOR gate. The XOR gate (sometimes EOR, or EXOR and pronounced as Exclusive OR) is a digital logic gate that gives a true (1 or HIGH) output when the number of true inputs is odd. An XOR gate implements an exclusive or; that is, a true output results if one, and only one, of the inputs to the gate is true.

What is or gate?

OR gate. The OR gate is a logic gate that outputs 1 (true) when at least one of its inputs is 1 (true). That means that if both of its inputs are 0, the output will be 0. The best way to remember an OR operation is “one or the other, or both.”.

What does the XOR operator do?

Short for eXclusive OR, the XOR operator is a Boolean operation used in database searches and other searches that returns a TRUE value only if a document contains only one match. In the above example, the command would return results of documents or a value that contain either “computer” or “help”.
