Let A and B is the input of a subtractor then the output will be ___________
A. A XOR B
B. A AND B
C. A OR B
D. A EXNOR B
Answer:A
Let A and B is the input of a subtractor then the output will be ___________
A. A XOR B B. A AND B C. A OR B D. A EXNOR B
Explanation: The subtractor has two outputs BOROW and DIFFERENCE. Since, the difference output of a subtractor is given by AB’ + BA’ and this is the output of a XOR gate. So, the final difference output is AB’ + BA’.
