1 Design A Sequential Logic Circuit That Can Function As The Basis For A Simple Electronic Lock The Circuit Is Reset T 1 (37.27 KiB) Viewed 66 times

I think I have to draw a mealy state graph, write a state
transition table and assign flip flops to get the final diagram as
asked, however I am confused on how to solve for this. Any
explanations to solutions would be great!
1) Design a sequential logic circuit that can function as the basis for a simple electronic lock. The circuit is reset to the initial state by pressing the push button SW4 on the board. To reach the final correct state, the buttons pushed down in the following sequence: SWI, SW2, SW2, SW3 (note these are active low in the push down position). Any other combination will cause the circuit to go to an error state after four buttons are pushed from which the circuit can only be removed by a reset with the push button SW4.
