1) [7 marks] You have been hired by a company to design a circuit to encrypt passwords. Assume passwords are 3 bits in size and that the encrypted password is the original password inverted (0's become 1's and 1's become 0's) and then add 3 (modulo 8 as we only have 3 bits). For example if the password is 000 , we invert it to give us 111 . We then add \( 3(7+3=10 \bmod \) \( 8=2 \) ) which makes the encrypted password 010 . Design and build a sequential circuit to perform the above function (using the procedure from your notes) using a T flip-flop in the highest order bit, a D flip-flop in the middle and a T flip-flop in the lowest order bit. You need to show the State Table, K-maps and draw the sequential circuit.
