The bits of the input 2] 1.a) Fill the following truth table that defines the relationship between the two 2-bit numbers [1] 1.b) Find the minterm expansion for each of the output bits directly from the truth table numbers and the comparator decision bits are as shown in the table: (total of 4 binary inputs) and the 2 comparison outputs. Realize the above outputs using the following 4-16 decoder and NAND gates. 12] 1.c) Inputs Numbers 2 Comparator outputs A1A0 B1B0 ASB A2 B 10g 12 13 149
