Assume a three-story hospital is built at Expo Center Karachi, and you are hired to design the logic circuit for the newly installed lift. The lift only stops at Ground, Second, Third Floors. The lift has one button (RUN), that can be turned into Up or Down position. When the switch is turned to the UP position (i.e. R=1), the lift goes upward from the Ground floor (i.e. 0) to the top floor (i.e. 3), and if the switch is turned to the DOWN position (i.e. R=0) it will go downward. Design this synchronous sequential circuit for this up-down counter using the JK-flip- flops. Perform all design steps, including state-diagram, state-table, K-map, minimized expressions and finally, the draw the logic circuit.
