Question

There are many situations in logic design in which simplification of logic expression is possible in terms of XOR and _________________ operations.

(a) X-NOR

(b) XOR

(c) NOR

(d) NAND

The question was asked by my school teacher while I was bunking the class.

My question is taken from Karnaugh Map in portion Boolean Algebra and Minimization Techniques and Logic Gates of Digital Circuits

Answer 1

Correct option is (a) X-NOR

Explanation: There are many situations in logic design in which simplification of logic expression is possible in terms of XOR and XNOR operations.

Expression of XOR : AB’ + A’B

Expression of XNOR : AB + A’B’
