The $SOP$ (sum of products) form of a Boolean function is $\sum (0,1,3,7,11)$, where inputs are $A,B,C,D$
($A$ is $MSB$, and $D$ is $LSB$). The equivalent minimized expression of the function is
- $(\overline{B}+C)(\overline{A}+C)(\overline{A}+\overline{B})(\overline{C}+D)$
- $(\overline{B}+C)(\overline{A}+C)(\overline{A}+\overline{C})(\overline{C}+D)$
- $(\overline{B}+C)(\overline{A}+C)(\overline{A}+\overline{C})(\overline{C}+\overline{D})$
- $(\overline{B}+C)(A+\overline{B})(\overline{A}+\overline{B})(\overline{C}+D)$
