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 mod 8 = 2) which makes the encrypted password 010. Design and build a sequential circuit (using the procedure from your notes) using 3 T flip-flops to perform the above function. You need to show the State Table, K-maps and draw the sequential circuit.

Question
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 mod
8 = 2) which makes the encrypted password 010. Design and build a sequential circuit (using
the procedure from your notes) using 3 T flip-flops to perform the above function. You need
to show the State Table, K-maps and draw the sequential circuit.
