A lock has two inputs, O to open the lock and C to close the lock. You are to design a

finite state machine $($FSM$)$ to control the lock. Your finite machine takes input from

three buttons, namely:

R $$ to close the lock

$0$ to enter digit $0$

$1$ to enter digit $1.$

O LOCK

C

R

$0$

$1$

FSM

The lock is to close whenever the reset button R is pressed. The lock is to be opened

whenever the password combination $110$ is entered via the buttons $0$ an $1.$

Your design should include a state diagram, a state table, the minimised boolean

equations and the full circuit.
