- 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.
