railway RRB JE (CBT I + CBT II) Mock Test 2024 Digital Electronics Combinational Circuits Comparators
For the 2-bit comparator circuit having inputs as A1A0 and B1B0, the Boolean expression for A = B output can be expressed as:
1
(A1⊙ B0) (A0 ⊙ B1)
2
(A1⊕ B1) (A0 ⊕ B0)
3
(A1⊙ B1) (A0 ⊙ B0)
4
(A1⊕ B0) (A0 ⊕ B1)
