Consider numbers represented in 4-bit gray code. Let h₃h₂h₁h_o be the gray code representation of a number n and let g₃g₂g₁g_o be the gray code of (n + 1) (modulo 16) value of the number. Which one of the following functions is correct? [2 marks]
(a) go(h₃h₂h₁h_o) = ∑ (1,2,3,6,10,13,14,15)
(a) g₁(h₃h₂h₁h_o) = ∑ (4,9,10,11,12,13,14,15)
(a) g₂(h₃h₂h₁h_o) = ∑ (2,4,5,6,7,12,13,15)
(a) g₃(h₃h₂h₁h_o) = ∑ (0,1,6,7,10,11,12,13)

We consider the addition of two 2’s complement numbers b_n-1b_n-2....b_o and
a_n-1a_n-2....a_o.A binary adder for adding unsigned binary numbers is used to add the two numbers. The sum is denoted by c_n-1c_n-2...c_o and the carry-out by c_out. Which one of the following options correctly identifies the overflow condition? [2 marks]

Consider a Boolean function f (w, x, y, z). suppose that exactly one of its inputs is allowed to change at a time. If the function happens to be true for two input vectors
i₁ = (w₁, x₁, y₁, z₁) and i₂ = (w₂, x₂, y₂, z₂) we would like the function to remain true as the input changes from i₁ to i₂ (i₁ and i₂ differ in exactly one bit position), without becoming false momentarily. Let f (w, x, y, z) = ∑(5,7,11,12,13,15). Which of the following cube covers of f will ensure that the required property is satisfied?

(A) wxz,wxy, xyz, xyz,wyz
(B) wxy,w xz,wyz
(C) wxyz , xz,wxyz
(D) wzy,wyz,wxz,wxz, xyz, xyz

Consider the circuit in the diagram. The Θ operator represents Ex-OR. The D flipflops
are initialized to zeroes (cleared).

The following data: 100110000 is supplied to the “data” terminal in nine clock cycles. After that the values of q₂q₁q_o are: [2 marks]
(A) 000
(B) 001
(C) 010
(D) 101
