Best Answer

The XOR (Exclusive Or) gate has a true output when the two inputs are different. When one input is true, the output is the inversion of the other. When one input is false, the output is the non-inversion of the other.

A B R

0 0 0

0 1 1

1 0 1

1 1 0

Look at the last two lines. You see that R is NOT B, but only when A is true. The same can be said of A; R is NOT A, but only when B is true.

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.


What logic gate is called any but not all?

XOR


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


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.


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.

Why the output of xor gate having inputs 111 is 0?

The out put of the xor gate is o when the input is 111 because of the inverter at the output of the or gate.A2XOR = Exclusive Or gate. This means that the output is only 'true', when only 1 of the inputs is 'true'. The exclusivity means that if another input is true, then the output stays 'false'. It will only switch on when only one input is on.


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) ) ;


How xor gate is linear?

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.


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?
