Design a FSM which controls a seven segment display. The FSM for this task should alternate between displaying 1, 2, 4, and 8, in that order, and without the application of any external input (in other words, you go from one state to another on just the tick of the clock). In order to accomplish this, the inputs to the seven segment display will be treated as outputs of your FSM. That is, your FSM will output the appropriate values of A, B, C, D, E, F, and G in order to represent the numbers of interest. This overall task is separated into a series of questions, which should be submitted digitally via the turnin command.

-

-Draw the finite state machine corresponding to this task.

-How many latches/flip-flops do you need to implement this state machine?

-Draw a single truth table representing the behavior of the state machine.
