You are required to design a digital circuit for a cookie vending machine. The machine sells cookie for 0.75 JD each. Assume that there are only 0.25, 0.50, and 1 JD coins (Hint! Three different switches can denote three different types of coins, respectively). With the total amount of input coins, two LED's (Green) should display the number of cookies that a user can buy (Max. 2 cookies). Whenever there is change after getting the cookie, the machine will turn on another LED (RED) to remind the users of changes. For example, if one 0.25 and one JD coins are inserted in the slot, turn on one of the Green LED's (to indicate the number of cookies) and the RED LED to signal the change. However, if only one 0.50 or one 0.25 are inserted in the slot, do not turn on any LED (that is no cookie no change). Design the logic circuit and show all steps. Show all details: 1- Truth Table.. 2- The simplified boolean expression 3- The Circuit Diagram.
