For XOR in the purely logical sense, see Exclusive disjunction. XOR can also be viewed as addition modulo 2. XOR represents the inequality function, i. Without it, if the circuit that provides inputs A and B does not have the proper driving capability, the output might not swing rail to rail or be severely slew-rate limited.

A correlator looking for in the data sequence would compare the incoming data bits against the target sequence at every possible offset while counting the number of matches zeros:.

Retrieved from ” https: An engineering approach to digital design. This makes it practically useful as a parity generator or a modulo-2 adder. This page was last edited on 24 Octoberat Since the trailing sum bit in this output is achieved with XOR, datasjeet preceding carry bit is calculated with an AND gate.

In this example, the best match occurs when the target sequence is offset by 1 bit and all five bits match. For the NOR constructions, the lower arrangement offers the advantage of a shorter propagation delay the time delay between an input changing and the output changing. A way to remember XOR is “one or the other but not both”. Both include four independent, two-input, XNOR gates.


However, it is rarely implemented this way in practice. Pseudo-random number PRN generators, specifically Linear feedback shift registersare defined in terms of the exclusive-or operation. Example half adder circuit diagram. The “Rss” resistor prevents shunting current directly from “A” and “B” to the output.

However, this approach requires five gates of three different kinds. This page was last edited on 19 Decemberat The two-input version implements logical equalitybehaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”. For the NAND constructions, the lower arrangement offers the advantage of a shorter propagation delay the time delay xog an input changing and the output changing.

Retrieved 6 May However, extending the concept of the binary logical operation to three inputs, the SN74S with two shared xir and four independent “A” datxsheet “B” inputs for its four outputs, was a device that followed the truth table:.

The result is a circuit that outputs a 1 when the number of 1s at its inputs is odd, and a 0 when the number of incoming 1s is even.

Introduction to Logic Gates

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. As a result, XOR gates are used to implement binary addition in computers. When searching for a specific bit pattern or PRN sequence in a very long data sequence, a series of XOR gates can be used to compare a string of bits from the data sequence against the target sequence in parallel.

By using this site, you agree to the Terms of Use and Privacy Policy. If a specific type of gate is not available, a circuit that implements the same function can be constructed from other available gates.

The behavior of XOR is summarized in the truth table shown on the right. Correlators are used in many communications 74866 such as CDMA receivers and decoders for error correction and channel codes. From Wikipedia, the free encyclopedia. This article is about XOR in the sense of an electronic logic gate e. From Wikipedia, the free encyclopedia. Here is a diagram of a pass transistor logic implementation of an XOR gate. Unsourced material may be challenged and removed.

The XOR logic gate can be used as a one-bit adder that adds any two bits together to output one bit. Webarchive template wayback links Commons category link is on Wikidata. By looking at the difference between the number of ones and zeros that come out of the bank of XOR gates, it is easy to see where the sequence occurs and whether or not it is inverted.
