NA

Correct Option: A

NA

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.

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

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.

X 1 = X (X nor) 1 = X·1 + X 1 = X
Hence alternative (B) is the correct answer.

Correct Option: B

X 1 = X (X nor) 1 = X·1 + X 1 = X
Hence alternative (B) is the correct answer.
