State Diagram

Four possible states $(2$ flip$-$flops required$)$

$S_0(00)$:$0$ cents, $S_1(01)$: $5$ cents, $S_2(10)$:$10$ cents,

$S_3(11)$: $15$ cents

Only in $S_3$ is the output $1($when the gum is released$)$

Reset required to reuse vending machine

Assume D flip$-$floos are used $[12$ marks$]$ Assume we want to design a circuit that will deliver a can of soda when the user

deposits $$4.$ The external inputs to this circuit will be loonies $($which are worth $$1-$ L$)$ and

toonies $($which are worth $$2-$ T$).$ Assume there no change given and there is only one coin

slot so it is not possible to insert a loonie and toonie at the same time.

The output $($y$)$ for this circuit will be a $1$ when enough money has been inserted and the can

of soda will be released.

Use the Vending Machine Example as an example,

design and implement a sequential circuit to deliver a can of soda using T flip$-$flops. You need

to show the State Diagram, State Table, K$-$maps and draw the sequential circuit.
