8/8pts Question 1 Using block diagram of 1-bit full adders create a 3-bit parallel adder (show all the connections between the adders and proper outputs Logic Q1jpg 4/9 pts Question 2 Consider your design, if the inputs to be added were 100, and 111, what will be the resulting sum output (Express the resulting sum in binary and base 8 using the least number of bits)? What will be the carry output (Express it only in binary using the least number of bits)? Logic Q2.jpg 8/8pts Question 3 Use the block diagram of only 1-bit full adder, 1 D flip-flop, and any other logic component to design a Serial adder. Logic Q3.jpg 0/8 pts Question 4 For your serial adder to work correctly what are all the timing considerations we have seen? (ie. how do we determine the proper clock length?)
