## Is XOR self-dual?

Particularly in the context of RFET-based circuits, the logic primitives used in XMGs— Majority and Xor gates, can better preserve self- duality as both, the majority-of-three and the odd-input Xor function, are self-dual.

What is the dual of X Y Z?

A function is said to be Self dual if and only if its dual is equivalent to the given function, i.e., if a given function is f(X, Y, Z) = (XY + YZ + ZX) then its dual is, fd(X, Y, Z) = (X + Y).

### How do you write a dual of a Boolean expression?

The dual of a Boolean or of a Boolean expression is obtained by applying 2 operations: replacing/interchanging the logical ORs by logical ANDs and vice versa and replacing/interchanging the logical 0s by logical 1s and vice versa.

How many Boolean functions of degree n are self-dual?

A Boolean function F is called self dual if and only if F(x1,x2,….. xn)=F(ˉx1,ˉx2,…. ˉxn). How many Boolean functions of degree n are self-dual ?…GO Book for GATECSE 2022.

## What is self-dual in graph theory?

A plane graph is said to be self-dual if it is isomorphic to its dual graph. The wheel graphs provide an infinite family of self-dual graphs coming from self-dual polyhedra (the pyramids). However, there also exist self-dual graphs that are not polyhedral, such as the one shown.

What is dual of a 1 A?

Operator/Variable and Their Duality

Operator / Variable Dual of the Operator

### What is dual expression?

The dual of a Boolean expression is the expression one obtains by interchanging addition and multiplication and interchanging 0’s and 1’s. The dual of the function F is denoted Fd. Theorem 1.6. 1 (Duality Principle).

What is the dual of A and B or C and D?

Thus Q = A’B’C’D’. That’s the same expression, of course. ◦by applying generalized DeMorgan to the first form. Q = (A + B + C + D)’, we find the dual of A+B+C+D to be ABCD, so Q = A’B’C’D’.

## What is a Boolean complement?

Boolean Complement is denoted by a bar on top , ” ¬ ” or by “Not”. This simply says the value is the opposite. Examples: Boolean Complement.

What is the dual of a function?

The dual of a Boolean expression is the expression one obtains by interchanging addition and multiplication and interchanging 0’s and 1’s. The dual of the function F is denoted Fd.

### Can a function be a dual of a Boolean expression?

(ABC , A’B’C’) are mutually exclusive terms. (AB’C , A’BC’) are mutually exclusive terms. Here n = number of Boolean variables in the function. For a function to be a self-dual function, the function must be a neutral function.

Is the XOR gate equivalent to the or function?

One element conspicuously missing from the set of Boolean operations is that of Exclusive-OR, often represented as XOR. Whereas the OR function is equivalent to Boolean addition, the AND function to Boolean multiplication, and the NOT function (inverter) to Boolean complementation, there is no direct Boolean equivalent for Exclusive-OR.

## How to represent the exclusive OR function in Boolean algebra?

However, there is a way to represent the Exclusive-OR function in terms of OR and AND, as has been shown in previous chapters: AB’ + A’B As a Boolean equivalency, this rule may be helpful in simplifying some Boolean expressions. Any expression following the AB’ + A’B form (two AND gates and an OR gate) may be replaced by a single Exclusive-OR gate.

How to make a function a self dual function?

Here n = number of Boolean variables in the function. For a function to be a self-dual function, the function must be a neutral function. For a function to be a neutral function, number of minterms must be equal to number of maxterms. So, we choose half of the terms i.e. 2 n / 2 = 2 n-1 terms.

Is XOR self-dual? Particularly in the context of RFET-based circuits, the logic primitives used in XMGs— Majority and Xor gates, can better preserve self- duality as both, the majority-of-three and the odd-input Xor function, are self-dual.
