Problem 1A)The gray code can be expressed as1if k=NotherwisekkkkkgbgbbB) 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 0011 13pppttFFtPath through two NANDs 44164223333pFFtPath through three NANDs 00444264222
