[Q1] Derive the state diagram, state table and flip-flops input values for a sequential circuit with two T-type flip flops (named A and B), and one external input x. The circuit will have following two conditions: [10] i. When x = 1, the state of the circuit remains the same. For example, if the present state is 00 and the designer gives 1 as input, then the next state will also be 00. When x = 0, the circuit goes through the state transitions from 00 to 01, from 01 to 11, from 11 to 10, and from 10 to 00
