A hidden passage is controlled by a redstone circuit for an adder which performs binary addition two bits at a time. He notes that it adds the inputs (x2i, y21) and (x2i+1, Y2i-1), the (2i)th and (2i+1)th bits of two binary numbers, and returns the sum as outputs s2i, S2+1. The addition is performed each clock cycle, starting from i = 0 until i = п 1, where n is the number of bits and 2 presumed to be even. For example, when adding x = 011010, and y number as x1:0 and y1:0 respectively. In this case, X1:0 is 10 and y1:0 = 01, and the carry bit co is 1. Our sum, s,0 is 00 and the next carry bit c, is 1. On the next clock cycle, we look at the next two 0110012, we take the first two bits of each bits, X3:2 = 10 and y3:2 = 10, so our sum s3-2 is 01, but we have a carry c4 1. Finally, our last addition to perform is on X5-4 = 01 and y5:4 = 01, with a carry bit c4 = 1. Our sum therefore is s54 = 11 with carry C6 = 0. Our final result of the addition is 1101002.

Question 2 Design a circuit diagram for the following comparator system that takes three 3-bit binary numbers [A, B and C] as inputs and outputs in the following fashion: Output=1; if A-5>2B Output=0; otherwise NB1: You need to show a gate level diagram for the comparator, meaning you cannot use block diagram of magnitude comparator. However, you may use block diagrams of any other ICs you require. NB2: Drawing the circuit diagram horizontally in your script may help you. NB3: You cannot change the equation. You must draw the circuit for the given equation.

3(a): Consider the following circuit, which uses two D flip-flops with falling edge triggers along with -bit full adder. The flip-flops are controlled by a single clock, C. Suppose C, Q0 and Q1 all initially have the value 0. First, fill in the blanks in the "i " = 0 (initial state)" row to show the values of D0 and D1 at this initial time (assume the results of the adder have had time to stabilize) . Next, show the values of Q0 , Q1, D0 , and D1 once they have stabilized after the ith falling edge of the clock, where i ranges from 1 to 4. Note that both the A and Carry In inputs of the adder are (Q not ) Q'0 not Q0 None of these first four rows should be the exactly the same.
