What type of logic circuit is represented by the figure shown below?(a) XOR(b) XNOR(c) AND(d) XANDI have been asked this question in unit test.My doubt stems from Combinational Circuits in chapter Combinational Circuits of Digital Circuits

Answer»

The correct ANSWER is (b) XNOR

Explanation: After SOLVING the circuit we get (A’B’)+AB as output, which is XNOR operation. Thus, it will PRODUCE 1 when inputs are even number of 1s or all 0s, and produce 0 when INPUT is odd number of 1s.
