#7.13

the contents of the The count is to be represented directly by counting starts when the control input C is asserted and stops whenever asserted. Assume that the next state from all unused states is the state for count in the sequence (i.e., the state for 3) p-flop The the P7.13. Design a counter that counts in the following sequence The count is to be represented directly by the contents of three D flip-flops. The counter is enabled by the input C. The count stops when C-0. The next state from all unused states are undefined. P7.14. Repeat Example 7.7, but with the following encodings. Which encoding results in the smallest FSM circuit? (a) Encode state s2 as 10 instead of 11, and encode the unused state as 11. de state so as 0001, s1 as 0010, s2 as 0100, and the unused state as 1000. All remaining combinations are unused and their next state is undefined. P7.15. Repeat Problem P7.13, but use a JK flip-flop, a D flip-flop, and a SR flip-flop in this order, starting from the most significant bit for the three flip-flops. 7.16. Manually design and implement on the UP2 board the following FSM circuit. Make the LEDs in the 7-segment display move in a clockwise direction around in a circle i.e., turn on and off the LED segments in this order: segment a, b, c, d, e, f, a, b, etc) 17, Manually design and imnlement on the TIP2 board the fol
