Exercises Use D, T, and JK FFs to design a three bit counter that has one input X. The counter count odd (1, 3, 5, 7) if X- 1, and counts even (0, 2, 4, 6) if X = 0. If the X = 0 and the current number is odd, the counter will go to the next even number. likewise, if X = 1 and the current number of even the counter goes to the next odd number. Design a 4 bit counters that goes through the following sequence: 0, 3, 5,2, 6, 1, 4, 8, 12, 11, 13, 7, 10, 14, 15, 9 0
