Question

In a finite state machine, state transitions happen only: a. When the reset causes a clock pulse on the D outputs of the flip-flops. 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.

Answer 1

Answer:

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 ).
