A combinational circuit has inputs A, B and C and its Karnaugh

Home » Digital Circuits » Digital circuits miscellaneous » Question

A combinational circuit has inputs A, B and C and its Karnaugh Map is as shown. The output of the circuit is given by

1. (AB + AB)C
2. (AB + AB)C
3. ABC
4. A ⊕ B ⊕ C

Correct Option: D

Output = A BC + A B C + ABC + A BC
= C (A B + A B) + C (AB + A B)
= A ⊕ B ⊕ C
