When XOR and XNOR give the same output?
we use only 2-input XOR/XNOR gates and cascade them to make the resultant gate n-input, then, if n is odd, having all gates XOR will give same output as having all gates XNOR. If n is even, they will give different outputs.
Why is XOR gate called odd function?
One of its most commonly used applications is as a basic logic comparator which produces a logic “1” output when its two input bits are not equal. Because of this, the exclusive-OR gate has an inequality status being known as an odd function.
Which gate generates a true output only if an odd number of inputs is true?
) from mathematical logic; that is, a true output results if one, and only one, of the inputs to the gate is true. If both inputs are false (0/LOW) or both are true, a false output results….XOR gate.
Input | Output | |
---|---|---|
1 | 1 | 0 |
Which gate is used for odd parity?
To generate even parity the bits of data are Exclusive-ORed together in groups of two until there is only a single output left. This output is the parity bit. To generate odd parity, simply invert the even parity. The last gate can be an Exclusive-NOR gate.
Is XNOR opposite of XOR?
The XOR function is only true if just one (and only one) of the input values is true, and false otherwise. XOR stands for eXclusive OR. As can be seen, the output values of XNOR are simply the inverse of the corresponding output values of XOR.
How do you expect the output of a 2 input XOR gate to behave?
The output of an XOR gate is true only when exactly one of its inputs is true. If both of an XOR gate’s inputs are false, or if both of its inputs are true, then the output of the XOR gate is false. If an XOR gate has more than two inputs, then its behavior depends on its implementation.
How does XOR behave for more than two inputs?
If both of an XOR gate’s inputs are false, or if both of its inputs are true, then the output of the XOR gate is false. If an XOR gate has more than two inputs, then its behavior depends on its implementation….XOR Gate.
Input A | Input B | Output |
---|---|---|
false | true | true |
true | false | true |
true | true | false |
What is Xnor function?
The XNOR gate (sometimes ENOR, EXNOR or NXOR and pronounced as Exclusive NOR. Alternatively XAND, pronounced Exclusive AND) is a digital logic gate whose function is the logical complement of the Exclusive OR (XOR) gate.
Which 3 input gate outputs a false value only when all inputs are true?
In digital electronics, a NAND gate (NOT-AND) is a logic gate which produces an output which is false only if all its inputs are true; thus its output is complement to that of an AND gate. A LOW (0) output results only if all the inputs to the gate are HIGH (1); if any input is LOW (0), a HIGH (1) output results.
Which gate depends on even and odd condition?

Is XNOR the same as and?
The two-input version implements logical equality, behaving according to the truth table to the right, and hence the gate is sometimes called an “equivalence gate”. A high output (1) results if both of the inputs to the gate are the same….XNOR gate.
Input | Output | |
---|---|---|
A | B | A XNOR B |
0 | 1 | 0 |
1 | 0 | 0 |
1 | 1 | 1 |
What is the inverse of XNOR?
XOR stands for eXclusive OR. As can be seen, the output values of XNOR are simply the inverse of the corresponding output values of XOR.
