design a sequential circuit to control the operation of a vending machine which dispenses a $0.25 product. I need a state diagram and a state table. please help! More info: The circuit has three inputs, N, D, Q, and two outputs, P and C. The coin detector mechanism in the vending machine is synchronized with that of the sequential circuit. The coin detector outputs a single 1 to the N, D, or Q input for every nickel, dime, or quarter, respectively that the customer inserts into the machine. Only one input will be 1 at a time. When the customer has inserted at least $0.25 in any combination of nickels, dimes and quarters, the vending machine must give change and dispense the product. The coin return mechanism gives change by returning nickels to the customer. For every 1 output on C, the coin return mechanism will return one nickel to the customer. The product is dispensed when the circuit outputs a single 1 on output P. The circuit should reset after dispensing the product.
