The University of Alabama in Huntsville Electrical and Computer Engineering CPE/EE 422/522 Spring 2005 Homework #5 Solution 3.2 (a)(10), (e)(20), 3.3(30), 3.6(20), 4.6(a)(20) 3.2 An older-model Thunderbird car has three left and three right tail lights, which flash in unique patterns to indicate left and right turns. Left-turn pattern: Right-turn pattern: LC LB LA RA RB RC LC LB LA RA RB RC Design a Moore sequential network to control these lights. The network has three inputs, LEFT, RIGHT, and HAZ. LEFT and RIGHT come from driver’s turn-signal switch and cannot be 1 at the same time. As indicated above, when LEFT = 1, the lights flash in a pattern LA on, LA and LB on, LA, LB, and LC on and all off; then the sequence repeats. When RIGHT = 1, the light sequence is similar. IF a switch from LEFT to RIGHT (or vice versa) occurs in the middle of a flashing sequence, the network should immediately go to the IDLE state (lights off) and then start the new sequence. HAZ comes from the hazard switch, and when HAZ = 1, all six lights flash on and off in unison. HAZ takes precedence if LEFT or RIGHT is also on. Assume that a clock

    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.
