Design and test a 4-bit ripple carry adder, i. e., an array of 4 full adders, that adds any 4-bit binary number A3A2A1A0 to the 8-4-2-1 BCD code of the third and fourth non-zero and different digits of your Red ID number. Select the BCD code for first the third and then the fourth digit using an array of 2-1 multiplexers with select input S. When S is zero, the 8-4-2-1 code for the third digit of your ID number (813006601) is added to A3A2A1A0 . When S is 1, the fourth digit is added to A3A2A1A0. Run through the 16 values of A3A2A1A0 for both S = 0 and S = 1. Use only AND, OR, and INV gates to create one full adder, and then copy to make 4 full adders. Do the same for the multiplexers. A3A2A1A0 will run from 0 to15 twice to make the exhaustive check.
