Both items cost 35 cents. The machine takes only dimes (D) and quarters (Q), one at a time. The machine operates as follows: • First, 35 cents have to be deposited. Then, select input G or C. If G or C is asserted before 35 cents have been deposited, nothing happens. • When input G is selected, G = 1 AND C = 0. When C is selected, G = 0 and C = 1. Assume that the sensors are designed in such a way that condition G = C = 1 will never occur. • The machine doesn't dispense any change. If you deposit 50 cents or 40 cents and select an item, you're out of 15 cents or 5 cents. The machine will keep the change. Draw the state transition diagram for the above machine in Mealy or Moore style. Note: Dime means 10 cents. Quarter means 25 cents.arrow_forward
