Problem 1 A) The gray code can be expressed as 1 if k=N otherwise kk kkk gb gbb  B) To create the XOR using NAND gates, The gray code circuit would like basically like Since the third bit has a delay of zero, I will include two inverters as a delay. Hence there are three paths: Path through two inverters b2->g2  00 11 1 3 pp p tt F F t  Path through two NANDs 4 4 16 4 22 33 3 3 p F F t     Path through three NANDs 0 0 4442 6 4 222
