E(x,y,z) = xyz + xyz' + x'yz' + x'y'z
Table de Karnaugh:
On "recouvre" les case occupées par des rectangles fondamentaux de surface maximale (implicants premiers)
Forme reduite: E(x,y,z) = xy + xz' + x'y'z
E(x,y,z) = xyz + xyz' + xy'z + x'yz + x'y'z
E(x,y,z) = xyz + xyz' + x'yz' + x'y'z' + x'y'z
E(x,y,z,t) = xyz't' + xyz't + xy'zt + xy'zt' + x'y'zt + x'y'zt' + x'yz't'
E(x,y,z,t) = xyzt' + xy' + x'y'
E(x,y,z,t) = xyzt + xyz't + xy'zt' + x'y' + x'yzt + x'yz't
