Mallard ECE 290: Computer Engineering I - Spring 2007 - Graded Web. .. https://mallard.cites.uiuc.edu/ECE290/webgrade.cgi?SessionID=mding3. .. 1 of 2 3/24/2007 6:39 PM Graded WebQuiz: Design a Gray Code Counter You have submitted this WebQuiz 2 times (including this time). You may submit this WebQuiz a total of 10 times and receive full credit. Question #1 In order to build a counter which counts from 0 to 12, the minimum number of flip-flops needed is: 4 You received a raw score of 100% on this question. Question #2 For this problem you will design a Gray code counter. The counting sequence is y 2 y 1 y 0 = 000, 001, 011, 010, 110, 111, 101, 100, 000, . ... The counter will have one input (x) which will be high when the counter is to descend ("count down") and low when not. For instance, when in state y 2 y 1 y 0 = 101, the next state will be 111 if x = 1 but will remain 101 if x = 0. Implement your design with 3 D flip-flops. You may refer to the
