In a finite state machine, state transitions happen only: a. When the reset causes a clock pulse on the D outputs of the flip-fl
ops. b. When the latches cause the Q inputs of the flip-flops to toggle. c. When there is a clock pulse. d. When the present state is the same as the next state. e. When the present state is causes the next state to reset.
When the present state is causes the next state to reset. ( e )
Explanation:
A finite state machine is a machine that can only be a certain state out its finite number of states at a given time. Hence state transitions occurs in a Finite state machine when the present state is causes the next state to reset.
An Example of a Finite state machine is a Coin-operated turnstile :
In this Finite state machine the Input of Coin unlocks the machine hence resetting the next state ( i.e. the lock state ), while to activate the lock state you push the arm of the Turnstile which in turn will as well reset the unlock state ( previous state ).
