    NA

    Correct Option: A

    NA


  1. An OR gate has 6 inputs. How many input words are there in its truth table?









  1. View Hint View Answer Discuss in Forum

    Number of input = 6
    Number of words = 26 = 64
    Hence alternative (C) is the correct answer.

    Correct Option: C

    Number of input = 6
    Number of words = 26 = 64
    Hence alternative (C) is the correct answer.



  1. An AND gate has 7 input. How many words are there in its truth table?









  1. View Hint View Answer Discuss in Forum

    Number of input = 7
    Number of words = Number of states = 27 = 128

    Correct Option: C

    Number of input = 7
    Number of words = Number of states = 27 = 128


  1. The output of the following circuit is given by—

    F1 = 0 (since both the input have same value i.e.,
    A ⊕ A = AA + AA = 0)
    F2 = A (since F1 ⊕ A ⇒ 0 ⊕ A = 0A + A0 = A
    F3 = 0 (since F2 ⊕ A ⇒ A ⊕ A = AA + AA = 0
    Hence alternative (B) is the correct answer.

    Correct Option: B


    F1 = 0 (since both the input have same value i.e.,
    A ⊕ A = AA + AA = 0)
    F2 = A (since F1 ⊕ A ⇒ 0 ⊕ A = 0A + A0 = A
    F3 = 0 (since F2 ⊕ A ⇒ A ⊕ A = AA + AA = 0
    Hence alternative (B) is the correct answer.



  1. The Boolean expression (XYZ + YZ + XZ) after simplification—









  1. View Hint View Answer Discuss in Forum

    Given expression = xyz + yz + xz = yz (x + 1) + xz = yz + xz = z (y + x) (after simplification)
    Hence alternative (D) is the correct answer.

    Correct Option: D

    Given expression = xyz + yz + xz = yz (x + 1) + xz = yz + xz = z (y + x) (after simplification)
    Hence alternative (D) is the correct answer.
