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.

Is xor gate is a universal gate?
No, XOR gate is a not a universal gate. There are basically two universal gates NAND and NOR.
Why XOR gate and XNOR gate are not universial gate?
xor and xnor gates are derived from not gate
Is xor gate is derived gate?
yes... xor is derived gate from primary gates
How many minimum number of nand gates are required to realize xor gates?
As such an OR gate should do the job...but if the question is of using gates other than the simple OR, it should be a combo of NOR and NOT gates; where-in, the NOT gate comes after the NOR gate. Factfully speaking: The output of a NOR gate when fed to a NOT gate shall give you an OR gate. cheers :) Anish Murthy Airpula, RF Design Engineer (F.A.E) Ceramic & Microwave Products Group, Dover Corporation Inc, United States of America
Making of X-nor gate with the help of ic?
the easiest way to make an xnor gate is with a 7486 (or equivalent) integrated circuit, a quad xor gate. connect the output of one gate to one in put of another gate. connect the other input of the second gate to Vcc. the second xor gate will then act as an inverter.
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 xor gate is linear?
its not
Why OR gate is an all gate?
XOR (Exclusive OR) gate is exclusively for either. OR allows 10, 01, 11. XOR allows 10 or 01, but not 11.
What is the major difference between arithmetic and logical operations?
Arithmetic operations are addition,subtraction,multiplication,division.Logical operations are OR,AND NOT,NOR,NAND,XOR,XNOR.
Why OR gate is an any-all gate?
XOR (Exclusive OR) gate is exclusively for either. OR allows 10, 01, 11. XOR allows 10 or 01, but not 11.
How many gates are used in XOR gate?
1 gate.
Any logical function can be implemented with only NOR gates?
Yes._____A----|_____NOR------QThis is an inverter. A NOR gate is an OR gate with an inverter on the end, so adding the above configuration after another NOR gate would give you an OR gate.__A----|__NOR---\__ NOR------QB----|__NOR---/This is an AND gate. By adding the inverter, you can get a NAND gate.A____|___|__NOR----------------\| | \| |___ NOR----QB __| |___NOR-----\ /|_____ NOR --/|_____NOR-----/By combining an AND gate, an OR gate, and a NAND gate, and canceling out a couple of inverters, you get this operator, which is a XOR gate.The formatting here is messed up, but if you go to the "improve answer" link, you can see the circuits.
