    In 4 × 1 MUX, A and B as select line, the truth table is

    Output = F = I0 – S1 – S2 + I1 – S2 S1
    F=I0 – S1 – S2 + I1 – S1 S2 + I2 – S1 S2 + I3 S1S2
    = C – A – B + C – A B + – C A – B + – C A B
    = C – A (B + – B) + – C A (– B + B)
    = C – A + – C A
    = C ⊕ A

    Correct Option: B

    In 4 × 1 MUX, A and B as select line, the truth table is

    F=I0 – S1 – S2 + I1 – S1 S2 + I2 – S1 S2 + I3 S1S2
    = C – A – B + C – A B + – C A – B + – C A B
    = C – A (B + – B) + – C A (– B + B)
    = C – A + – C A
    = C ⊕ A

  1. For the logic ckt circuit below, the output Y is equal to—

    Y = A + C + B + AC
    = A (C + 1) + C + B
    = A + B + C

    Correct Option: B


    Y = A + C + B + AC
    = A (C + 1) + C + B
    = A + B + C
