Question

This sentence goes after the last sentence in the picture.( You should determine the combinational logic needed to implement the converter before class tomorrow.)

Can you do it for me please?

Part 1: One of the earliest and simplest encryption techniques was the substitution cipher in which individual letters and numbers (plaintext) are replaced with other letters and numbers (ciphertext) according to a fixed system. In this assignment, you will design and build a converter that that takes a decimal input and converts it to a bit-inverted four-bit Gray code (b3-b0). Then, a fifth bit is added (b4) that ill permit an odd parity check.
