Unformatted text preview: a and b . Let us refer to the LSB of a is a , and the LSB of b as b . The result is referred to as c . The adder is built using only AND, OR or INV gates. (a) Assume that a is an M bit number, and b is an N bit number. Both a and b are unsigned. What is the number of bits in c ? (b) Suppose M is 3 and N is 5. Draw a ripple carry adder circuit which implements c . Do not use half-adders in your design. (c) How many gates does your adder of the previous part utilize? (d) If you were allowed to use half adders, what is the minimum number of gates that your adder needs? 1...
