Design a left-shift register similar to that of Figure
Chapter 12, Problem 12.12(choose chapter or problem)
Design a left-shift register similar to that of Figure 12-10. Your register should shift left if Sh = 1, load if Sh = 0 and L = 1, and hold its state if Sh = L = 0.
(a) Draw the circuit using four D flip-flops and four 4-to-1 MUXes.
(b) Give the next-state equations for the flip-flops.
