Question

In case of XOR/XNOR simplification we have to look for the following _______________

(a) Diagonal Adjacencies

(b) Offset Adjacencies

(c) Straight Adjacencies

(d) Both diagonal and offset adjencies

The question was posed to me in class test.

I want to ask this question from Karnaugh Map in portion Boolean Algebra and Minimization Techniques and Logic Gates of Digital Circuits

Answer 1

The correct choice is (d) Both diagonal and offset adjencies

To elaborate: In case of XOR/XNOR simplification we have to look for the following diagonal and offset adjacencies. XOR gives output 1 when odd number of 1s are present in input while XNOR gives output 1 when even number of 1s or all 0s are present in input.
