Tabular Method of Minimisation - Answers


  1. Consider the function: Z = f(A,B,C,D) = + C + ACD + AC + BCD + BC + CD

    Convert to decimal and binary equivalents:-

    Z = f(A,B,C,D) = (0,2,4,5,8,9,12) - decimal equivalent

    Z = f(A,B,C,D) = (0000,0010,0100,0101,1000,1001,1100) - binary equivalent

    (0, 1, 1, 2, 1, 2, 2) - index values

    The simplified answer is: Z = + B + A +




  2. Note that the remaining term 12 is covered by B and AB

    One simplified answer is: Z = + AC + B
    Another answer is: Z = + AC + AB
