The system must 3 min asynchronously go to state "2" when Restart (active-high) goes true. W is an active-low signal that determines the next "count" after "0," as Restart shown in the figure. Use a T-FF for the most significant bit of your design, W = L. a JK-FF for the least significant bit, and D-FF(s) for any other bits you might need. An active-low output, Y should be true when the "count" is 5 "5." All other outputs should be active-high. Note: All the given FFs have W=0 asynchronous clear and set inputs as shown. (2%) a) Draw a functional block diagram (showing all the inputs, all the outputs, 4 min and the functional blocks). Put your design in the dashed box with the inputs and outputs going into or out of the box, on the left or right, respectively. This is not a circuit diagram.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
