In this problem, you will design a 3-bit circular shift register using D flip-flops. A circular shift register is one that takes the value of the bit that is shifted out and uses it to replace the bit that is shifted in. For example, the binary number 101 shifted to the right would give 110 and shifted to the left would give 011. There should be two select variables so and s to control the behavior of this shift register The first (so) is an enable variable that holds the values on the flip flops when so0 and shifts the values when 80-1. The second select variable controls whether the shift register shifts to the left whens-0) or to the right (s1. Include a state table and a circuit diagram
