You are tasked to design a control unit for a light display. The light display design has three light components, see Figure 4.1a. Design a state machine that will control the sequence of the display (see Figure 4.1b). Your design should include three edge triggered D flip-flops, with each of the components controlled by one D flip-flop. Individual states of the sequence have been pre-defined (see Figure 4.1b), and the sequence should be run as an infinite loop. Any unused states can be treated as Don’t Cares. Your answer should include the following: a) A state diagram for the monitoring unit. b) A transition table. c) Based on the transition table in part b), use Karnaugh Maps to derive input equations the three D flip-flops.
