Given f(x,y,z)=sum(1,2,3,4)
draw truth table
find product of sum exprsn
find max terms
find sum of product
truth table
x y z out
0 0 0 0 (x'+y'+z')
0 0 1 1 x'y'z
0 1 0 1 x'yz'
0 1 1 1 x'yz
1 0 0 1 xy'z'
1 0 1 0 (x+y'+z)
1 1 0 0 (x+y+z')
1 1 1 0 (x+y+z)
sop=x'y'z +x'yz' +x'yz +xy'z'
pos=(x'+y'+z')(x+y'+z)(x+y+z')(x+y+z)
i think this is incorrect and i don't knw how to find the max terms
