Exclusive Or means "one and only one of many", so the truth table of a 3 input XOR gate would be
000 0
001 1
010 1
011 0
100 1
101 0
110 0
111 0 ... or 111 1 ... see note
Many references say that 3 input XOR gate's output should be 1 when the no of 1s in inputs is Odd, and 0 otherwise. So in the given truth table, when the input is 111 output must be 1 , i.e. 111 1
plz note -- for 111 1 must be the optput.. i confirmed it

How do you write the Boolean expression for XOR gate?
For 2-input EX-OR gate, if one input is A, the other input is B, and the output is Y. Then the Boolean expression for EX-OR (XOR) function (gate) is Y=A⊕B The output Y is true if either input A or if input B is true, but not both.Y= ( (A and NOT B) or (NOT A and B) ) ;
Full subtractor circuit using x-or gate?
To make a full subtractor, you need an XOR and a NAND gate.
What is the ic number of xor gate?
CD4070BE, SN74HC86N, SN74ACT86N, SN74LS86AN, CD74ACT86E, and CD74HCT86E are some of them
Is xor a even function?
XOR is odd functionfor more details uoy can visit :-faculty.kfupm.edu.sa/coe/aimane/coe202/XOR_XNOR.pdfANSWER: Exclusive OR gate will pass out a low or 0 when both input are zero 0 OR both inputs are HI 1. All other time is just hi 1.that is the logical premise or functionY =A(+) B = A not B + A Bnot
What are applications of XOR gate?
It can be used as memory, it remembers the input of for instance A if the other input is 0. For example:A0XOR000101It is used to check the parity of received bits, in other words to checks the correctness of the data received (See Hamming fault correction) and can find and correct faults in a byte if there is only one fault.It can also be used as a bit-flipper if one input is A and the other is 1. For example:A1XOR011110
Is oit possible to use three input in ic 7486?
If you look at the 7486 IC datasheet you can see, it have 4 independence XOR gates with 2 inputs. So you can only use 2 inputs if you see it like that. But if you understand the truth table of XOR gate you can have 3 input application using 7486 IC. Here I will show you how. 1.Get the first 2 input into the first XOR gate. 2.Then get the 3rd input together with the Output from the first 2 input XOR gate into another gate. 3.This output should be the result of 3 input XOR gate. Check this output with 3 input truth table to confirm the answer.

Truth table for 3 input xnor gate?
A, B and C are inputs, Q is output.A B C Q0 0 0 10 0 1 00 1 0 00 1 1 11 0 0 01 0 1 11 1 0 11 1 1 0*update*Although the Logism software shows the 3 input XNOR gate output 1 when all 3 are 1, perhaps there is a mistake, and 3 input of 1,1,1 in an XNOR gateoutputs 0. There is a good reason why. In an XOR gate, an even amount of 1 or 0 input will output a 0, and an odd input of 1 (ie: 1, 1, 1) will output a 1. The truth tablefor an XOR gate with 1, 1, 1 input is an output of 1. An XNOR gate will output the opposite of an XOR gate, thus XNOR input of1, 1, 1 should output 0.
How From the truth table of an X-OR gate write the X-OR equivalent equation by using NOT OR and AND gate?
a XOR bis equivalent to: (a AND NOT b) OR (b AND NOT a)
What are the difference between NOR gate and XOR gate?
Truth table of 'NOR' is 0 0 - 1 0 1 - 0 1 0 - 0 1 1 - 0 NOR is just opposite of OR as the name itself suggest NOR is the not of OR. Whole XOR is 1 for different outputs and 0 for same outputs.
Why XOR and XNOR gate is not known as universal gates?
All other logic gates can be made using XOR and XNOR, but to get NOT, you need to do (input) XOR 1 or (input) XNOR 0, but with NAND, you don't need 1: (input) NAND (input).
How using two-input logic gates of your choice design a circuit to determine if two 3-bit numbers are the same or different?
Three 2-input XOR gates and one 3-input NOR gate will do the work. Connect each output of each XOR gate to one input of the 3-input NOR gate and apply the two 3-bit words to the inputs of the XOR gates. If X (X2X1X0) and Y(Y2Y1Y0) are two 3-bit words, X2 and Y2 will connect to one XOR gate, X1 and Y1 to the next XOR gate and X0 and Y0 to the last XOR gate. You could see the result of the operation on a LED connected to the output of the NOR gate. Other implementations are also possible of course. The solution above is absolutely correct, but includes a 3 input gate. If the task is to use only two input gates, then a small change will be needed. Take the outputs from any two XOR gates into a 2 input OR gate. Then take the output of the OR gate and the output of the third XOR gate into a 2 input NOR gate. The operation remains identical to the first solution but adheres to the brief of using gates with 2 inputs. In the real world, there is probably no reason to impose such a limitation on a design so the first solution would normally be the preferred route to take.
How do you construct a 3 ip nand gate using only 2 ip nand gates?
To produce a 3-input OR gate when only 2-input OR gates are available: Use 3 OR gates Inputs to Gate A are input 1 and input 2 Input to Gate B is input 3 (if 2 inputs are necessary, include input 3 and FALSE) Inputs to Gate C are outputs from Gate 1 and Gate 2 === If input 1 OR 2 is TRUE, output of Gate A will be TRUE. If input 3 is TRUE, output of Gate B will be TRUE. If output of Gate A OR Gate B is TRUE, output from Gate C will be TRUE. That is if one ore more of Inputs 1, 2 or 3 is TRUE, the result will be TRUE. Otherwise, output of Gate C will be FALSE.
What is he Boolean expression for 3 input XOR gate?
Out= A'B'C+AB'C'+AC'A'+ABC
Why XOR gate and XNOR gate are not universial gate?
xor and xnor gates are derived from not gate
Operation of XOR gate?
An XOR (exclusive OR gate) has two inputs and one output. If only one of the inputs is at level 1, then the output is 1 otherwise the output is 0. The truth table looks like this: A B Out0 0 00 1 11 0 11 1 0 Exclusive OR represents in logic what "or" means in English; for example, if asked if you want tea or coffee it's usually meant that you can have one or the other - not both.
Is xor gate is derived gate?
yes... xor is derived gate from primary gates
