Q2 part 1

QUESTION 2 (35 POINTS) Design a sequential circuit using T Flip-Flops. The sequential circuit has three states S1, S2 and S3, one input X, and one output Y. As long as the input X is 'O', the circuit alternates between the states S2 and 53. If the input X becomes 'l' (either in state S2 or in state S3), the circuit goes to state S1 and remains in state S1 as long as X continues to be '1'. The circuit returns to state S2 if the input becomes 'O' once again and from then on repeats its behavior. The output Y=l if there is a transition to a new state, otherwise 0. Assume that the state assignments are SI = 00, S2 = 01 and S3 = 10. 1) Draw the state diagram of the sequential circuit. (10 points)
