Design a counter that counts the following sequence of 2-3-1-0 and repeat. Use JK flip-flops given to you at the start of the semester. These values will be displayed on a seven-segment display like the one used in Lab 3. For input and output circuits, you may use any chips available in the lab, but you must justify your choice, both of your design and of the flip flops you use (combinational logic, decoder, or PLD). You must demonstrate your counter using your 7-segment display and any additional logic gates/devices that you need to control the circuit. Note that in a circuit using edge-triggered flip-flops, it may be necessary to use a debounced switch as the clock. Find a suitable circuit that can be built with the items available in our lab (either online or in a text), and include it, and a proper reference for it, with your prelab. A debounced switch can take the place of a clock, but you will have to manually flip the switch.
The prelab you turn in in the lab must include the state table and state diagram for your design, Karnaugh maps (or whatever documentation is required to support your design) and a schematic of your circuit, (with all pins and gates labeled), along with the debounced switch you found, and the reference to it. NOTE: the debounced switch design must be done before you come to the lab.
