4. Design a circuit that accepts a three bit input, which we will view as a string, and as output delivers the string after a circular shift to the right. If you are not familiar with this shift, it's fairly simple. Each bit in the string moves one position to the right, and the bit that would normally fall off of the right end is brought around to the left side of the string. Examples: if input combination is 001, output is 100; if input is 011, output is 101; if input is 101, output is 110; etc. Draw the logic diagram. (1 point for design, 1 point for diagram)
