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.

Depending on X which is the last digit of your student number, implement the followingfunction F by using one 8-to-1 multiplexer. F(A, B, C, D) = Σm(X-4, X-1, X, X+1, 13, 14, 15) x=8
In this problem, you will design a circuit that encrypts (plaintext to cipher) and decrypts (cipher to plaintext) ASCII characters. The relationship between the plaintext character and cipher character is shown in the table below: plaintext character cipher character 1-? A-O P-Z space t-~ 0 In this table, the "0" and "1" refer to the characters "0" and "1", not the numerical values. Additionally, the circuit only needs to account for character listed in the table. The circuit has nine bits of input: • d = d7... do: an eight-bit number that is the binary representation of the input ASCII character • e: a single bit indicating if the circuit should encrypt (e = 1) or decrypt (e = 0) the given character The circuit has eight bits of output: • r = r7...ro: an eight-bit number that is the binary representation of the output ASCII character Draw the implementation of the circuit. The circuit does not have to be transistor-minimal; you are encouraged to use various combinational circuitry to…

Later, the student uses the oscillator to create a single pulse with initial speed vo at at the left end of the string, as shown above. The student wants to quantify the observation that the pulse slows down on the right half of the string. The student comes up with the following equation relating the string’s diameter D at a given point on the string to the speed v of the pulse at that point: v=vo(Do/D) (c) Is the equation consistent with the observation that the pulse slows down on the right half of the string? ____Yes ____No (d) Using frame-by-frame analysis of video of the pulse, the student plots the speed v of the pulse as a function of the string diameter D, as shown below.
