In the faculty of electronics, argumentation agency that the ambit works using alone two voltage levels - top and

Logic gates are accessories that can amalgamate assorted inputs at absolute argumentation levels and appear up with an achievement accordingly. There are some kinds of argumentation gate, and the acumen lies in that anniversary affectionate processes the inputs differently, and may accord altered ouputs for the aforementioned inputs.

The way the argumentation aboideau processes altered inputs is accustomed in a accuracy table for that gate, which lists all the accessible combinations of inputs next to their outputs. An archetype is accustomed for a simple one-input aboideau with the action of giving the adverse argumentation akin at the achievement to the one at the input. The inputs are accustomed on the left, and the outputs are on the right. Generally, the inputs are alleged A, B, C, etc., and the achievement is labelled Q. In this case, there are alone two accessible inputs, 1 or 0, but argumentation gates can accept any amount of inputs.

There are seven kinds of argumentation gates, and anniversary of these will be declared be low . Anniversary affectionate of argumentation aboideau has a ambit attribute associated with it. In fact, there are several adverse standards defining the symbols for argumentation gates. The accepted symbols are ANSI symbols, sometimes alleged the MIL symbols. These are the alotof characteristic and are broadly acclimated and recognised. It is recommended to use these symbols, and this wikibook will use them to the exclusion of the others. The allegory amid the three attribute sets is accustomed .

Boolean algebra is a way to mathematically accurate analytic operations performed on data. There are symbols for the operations performed by anniversary argumentation gate, and these are accustomed in the accordant sections be low . It uses several symbols that are not about acclimated anywhere else, and the use of these will be aswell be explained be low . Boolean algebra can be acclimated to represent several analytic operations done at once, and this be explained in .

Each affectionate of aboideau has its own attribute acclimated if autograph the functions down, but ideally, alone the symbols for NOT, AND, OR and XOR are used, to abate confusion, and to affluence .

A NOT aboideau or an inverter is the simplest affectionate of argumentation gate. Its action is to accord the adverse achievement to its ascribe - if it gets a high, it gives a low , and carnality versa. This is agnate to adage that the achievement is not the input.

The ambit symbol, left, for a NOT aboideau is a triangle with the point adverse appear the output, and a amphitheater at the output.

The boolean attribute for the NOT abettor is either a band over the accordant input, or a ¬ attribute above-mentioned it. Thus, the account that the output, Q, is not the input, A, is either

::$ar=Q$ or $$

eg A = Q,

For instructions on how to address this in Wikitext or HTML, see .

NOT gates can be implemented in a array of ways. See the afterward for added information:

An AND aboideau gives a top achievement alone if both inputs are high. If one or added inputs are low , then the achievement is aswell low . This is agnate to adage that the achievement is top if one ascribe and the additional one are high.

The ambit symbol, left, for an AND aboideau is a box with one ellipsoidal end (inputs) and one semi-circular end (output).

Boolean multiplication is agnate to the AND action (see why Thus, the AND aboideau can be represented by a multiplication dot · or just putting the two agreement together.

::$A\; cdot\; B=Q$ or $AB=Q\; ,$.

For instructions on how to address this in Wikitext or HTML, see

See the afterward for added advice on the accomplishing of AND gates:

A NAND aboideau gives a low achievement alone if both inputs are high. If one or added inputs is high, then the achievement is low. This is agnate to adage that the achievement is NOT the achievement of an AND aboideau presented with the aforementioned inputs. This NOT AND aggregate is beneath to just NAND.

The ambit symbol, left, for an NAND aboideau is a box with one ellipsoidal end (inputs) and one semi-circular end (output). This achievement end has a baby circle, cogent an inversion.

The boolean attribute for the NAND abettor is a vertical band (the Sheffer Stroke). Thus, the NAND aboideau can be represented by the boolean statement

::$A\; |\; B=Q\; ,$

NAND can aswell be accounting as the antithesis (NOT) of the AND:

::$overline\; =Q$ or $overline\; =Q\; ,$.

This is the prefered notation, as it is easier to see what is accident in agreement of the basal functions.

See the afterward for added advice on the accomplishing of AND gates:

NAND gates accept the acreage that any additional argumentation aboideau can be approach from just NAND gates. For the adjustment of accomplishing this, see .

An OR aboideau gives a top achievement if any ascribe is high. If all inputs are low, then the achievement is low. This is agnate to adage that the achievement is top alone if if one OR the additional OR both inputs are high.

The ambit symbol, left, for an OR aboideau is agnate to that of an AND gate, but with a acicular end (ouptuts) and a biconcave end (inputs).

Boolean accession is eqivalent to the OR action (see why Thus, the OR aboideau can be represented by a additional assurance (+):

::$A\; +\; B=Q\; ,$

A V-shaped attribute can aswell be used, but it is not accepted and should not about be used.

::$A\; lor\; B=Q\; ,$

See the afterward for added advice on the accomplishing of OR gates:

A NOR aboideau gives a top achievement alone if no inputs are high. If an ascribe is high, then the achievement is low. This is agnate to adage that the achievement is top alone if if neither one NOR the additional ascribe is high. It is the adverse to an OR gate.

The ambit symbol, left, for a NOR aboideau is agnate to that of an OR gate, but for the accession of a amphitheater to denote the antagonism from an OR gate.

NOR can aswell be accounting as the antithesis (NOT) of the OR:

::$overline\; =Q$.

This is the adopted notation. Addition attribute for the NOR abettor is a attribute like ?, which can be acclimated if the band over the top cannot calmly be fatigued (e.g. in accustomed argument like this):

::$A\; perp\; B=Q\; ,$

See the afterward for added advice on the accomplishing of NOR gates:

NOR gates accept the acreage that any additional argumentation aboideau can be approach from just NOR gates. For the adjustment of accomplishing this, see .

An XOR aboideau abbreviate for exclusive-OR, gives a top achievement if one ascribe is top and the additional is low. If both inputs are the same, the achievement is low. This is agnate to adage that the achievement is top alone if one OR the additional but not both inputs are high.

The ambit symbol, left, for an XOR aboideau is agnate to that of an OR gate, but with a bifold band at the biconcave ascribe end.

The boolean attribute for the XOR abettor is a plus-sign in a amphitheater or, because it alone allotment a top if the inputs are different,a not-equal-to assurance (not about used). Thus, the XOR aboideau can be represented by the boolean statements

::$A\; oplus\; B=Q\; ,$ or $A$

e B=Q ,

For instructions on how to address this in Wikitext or HTML, see

See the afterward for added advice on the accomplishing of XOR gates:

An XNOR aboideau abbreviate for exclusive-NOR, gives a top achievement if both outputs are the aforementioned - it is the adverse of the XOR gate.

The ambit symbol, left, for an XNOR aboideau is agnate to that of an XOR gate, but it has a amphitheater apery the antagonism at the ouput.

XNOR is accounting as the antithesis of the XOR function:

::$overline=Q$

As the XNOR action alone allotment a one if both inputs are the same, the boolean attribute for the XNOR abettor is an equalvalent-to assurance (?) assurance (not equals) in accustomed text. Because this looks actual abundant like an equals assurance it is calmly mistaken and should not be acclimated area possible.

::$A\; equiv\; B=Q\; ,$

See the afterward for added advice on the accomplishing of XNOR gates:

Logic gates affirm alotof of agenda electronics, (indeed the absolute on-board computer in the Apollo aircraft was create of NOR gates).

The alotof accessible uses is for simple control. Brainstorm designing a abrasion apparatus so that the baptize alone turns on if the abrasion is loaded (logic-1), the aperture is bankrupt (logic-1) but the clothes are not yet wet (logic-0). This can be done by ANDing the first two conditions, and inverting the third. Now, AND these together, and you get a top alone if all three altitude are satified.

By using just three argumentation gates (and, at alotof two ICs - one 4081 and one 4049), the problem has been solved.

However, argumentation gates are aswell acclimated to create and additional basic cyberbanking components.

One acceptable use of them is as which acquiesce a arresting to canyon alone beneath assertive conditions.

In the faculty of electronics, argumentation agency that the ambit works using alone two voltage levels - top and

**low**(or on/off, true/false or 1/0). These voltage levels are sometimes alleged argumentation levels and**agenda**circuits use alone these argumentation levels to represent information.Logic gates are accessories that can amalgamate assorted inputs at absolute argumentation levels and appear up with an achievement accordingly.
