Mallard ECE 290: Computer Engineering I - Spring 2007 - Graded Web. .. https://mallard.cites.uiuc.edu/ECE290/webgrade.cgi?SessionID=mding3. .. 1 of 2 2/16/2007 5:17 PM Graded WebQuiz: Decoders You have submitted this WebQuiz 1 time (including this time). You may submit this WebQuiz a total of 10 times and receive full credit. Question #1 For the decoder circuit drawn above, you are to give a canonical POS expression for F and canonical SOP expressions for both G and F. Express your answers using AND(Mi) or OR(mi) notation. F(x,y,z)= AND(M0, M3, M2, M7) G(x,y,z)= OR(m5, m4, m7) F(x,y,z)= OR(m1, m4, m5, m6) You received a raw score of 100% on this question. Question #2 A decoder can be implemented from smaller decoders using the general "shape" shown in the figure to the right. A 5:32 decoder can be constructed using 4 (how many?) 3:8 decoders with enable. Each of these decoders has inputs A 2 ... A 0 (specify address bit subscripts; e.g. A9 . .. A1) A single decoder of size 2 : 4 selects the appropriate one of these 3:8 decoders.
