Help me to answer this question Thank You !

(b) Moore machine can be converted into Mealy machine and vice verse. Figure Q2(b) shows the state diagram for one of the FSM model. Convert the state diagram into another FSM model. [4 marks] (c) The UVW Company has recently received an order for their all-digital Padlock (ADP). The ADP has two buttons (" 0 " and " 1 ") that when pressed cause the FSM controlling the lock to advance to a new state. In addition to advancing the FSM, each button press is encoded on the B signal (B=0 for button " (",B=1 for button " 1 "). The padlock unlocks when the FSM sets the UNLOCK output signal to 1 , which it does whenever the last 3 button presses correspond to the 3 -digit combination. Therefore, define the 3 -digit combination to unlock the padlock and then design the circuit diagram for this ADP by using T flip-flops. [17 marks]
