please solve number 4. Do not copy and paste from a different post.
(14 points) Design an up/down counter that has an input switch x and counts as follows: If x = 0, the counter counts 1, 2, 3, 4, 5, 6, 7 and repeats If x = 1, the counter counts 7, 6, 5, 4, 3, 2, 1 and repeats The counter should be designed using D flip-flops and using the state equation method. (No credit will be given if the circuit is designed using the excitation table method.) Draw the final logic diagram. Note that count 0 is unused and should be treated as a "don't care" state. 3. (14 points) Repeat problem 2 except using JK flip-flops and using the state equation method. (No credit will be given if the circuit is designed using the excitation table method.) Draw the final logic diagram. 4. (14 points) Repeat problem 2 using D flip-flops and the "one-hot" method. Draw the ASM chart and the final logic diagram.
