Quiz 1 Solution 1.(a) -23 101001 + 11 001011 -12 110100 no overflow (b) -18 101110 + -17 101111 1011101 overflow 2. F = AB’ + CD’ +E = ( AB’ + E + C ) ( AB’ + E + D’) = ( B’ + E + C )( A + E + C )(A + E + D’)(B’ + E + D’) 3. 左式 = (xy’ + x’y) z = (xy’ + x’y)’z + (xy’ + x’y)z’ = xyz + x’y’z + xy’z’ + x’yz’ => min SOP = x(yz + y’z’) + x’(yz’ + y’z)
