Question

A digital combination lock has four states: closed, 1/3 open, 2/3 open, and
open. It is opened using the correct series of three-bit binary entries. When in the closed
state, entering 001 moves it to the 1/3 open state. From there, 101 moves it to the 2/3
open state, but any other entry moves it back to closed. From 2/3 open, 011 moves it to
open (and any other entry moves back to closed). When in the open state, the lock should
generate an output Y which is true (which controls a solenoid that opens the lock). Then
the lock automatically moves to the closed state.

a)Draw the State Machine diagram


b)Create the state table


d)Design the digital lock using the D flip-flops
