Given the zhegalkin polynomial, find the boolean function

  1. Apr 2, 2017 #1
    1. The problem statement, all variables and given/known data
    the given zhegalkin polynomial is y=x1+x2.
    find the corresponding boolean functio

    3. The attempt at a solution
    zhegalkin polynomial for 2 variables is:
    f(x) = c12*x1*x2 + c1*x1 + c2*x2 + c
    => c12=0, c1=1, c2=1, c=0.
    therefore,
    f(0,0) = c = 0,
    f(0,1) = c2+c = 1+0 = 1
    f(1,0) = c1+c = 1+0 = 1
    f(1,1) = c1+c2+0 = 1+1+1 = 0
    => the boolean function should be xor?

    y=x1 mod2sum x2 is in the answers but the answer chosen as correct
    is y=x1 mod2sum x2 mod2sum x1x2. which one is correct?

    p.s. mod2sum is "+ in circle"
